Streszczenie:
Conventional strategies for materials design have long been used by leveraging primary bonding, such as covalent, ionic, and metallic bonds, between constituent atoms. However, bond energy required to break primary bonds is high. Therefore, high temperatures and enormous energy consumption are often required in processing and manufacturing such materials. On the contrary, intermolecular bonds (hydrogen bonds, van der Waals forces, electrostatic interactions, imine bonds, etc.) formed between different molecules and functional groups are relatively weaker than primary bonds. They, thus, require less energy to break and reform. Moreover, intermolecular bonds can form at considerably longer bond lengths between two groups with no constraint on a specific bond angle between them, a feature that primary bonds lack. These features motivate unconventional strategies for the material design by tuning the intermolecular bonding between constituent atoms or groups to achieve superior physical properties. This paper reviews recent development in such strategies that utilize intermolecular bonding and analyzes how such design strategies lead to enhanced thermal stability and mechanical properties of the resulting materials. The applications of the materials designed and fabricated by tuning the intermolecular bonding are also summarized, along with major challenges that remain and future perspectives that call for further attention to maximize the potential of programming material properties by tuning intermolecular bonding.

A series of imidazole derivatives (1-3) were synthesized with three component reaction among benzil, ammonium acetate and formaldehyde/aromatic aldehyde at 110 °C without a catalyst and solvent. These synthesized imidazole derivatives have shown intermolecular hydrogen bonding such as N-H···N and O-H···N. The imidazole 1 and 2 exhibited N-H···N intermolecular hydrogen bonding while imidazole 3 exhibited O-H···N intermolecular hydrogen bonding. The hydrogen bonds in imidazoles were studied by X-ray crystallography and Hirshfeld Surface Analysis at dnorm surface which show the visible red spots, indicated for hydrogen bonds. Further, Hirshfeld surface analysis also shows the percentage of all intermolecular interactions.

Streszczenie:
Computation of accurate hydrogen bonding energies in peptides is of great importance in understanding the conformational stabilities of peptides. In this paper, the intramolecular 8- and 12-membered ring N – H … O = C hydrogen bonding energies in β-peptide structures were evaluated. The optimal structures of the β-peptide conformers were obtained using MP2/6-31G(d) method. The MP2/6-311++G(d,p) calculations were then carried out to evaluate the single-point energies. The results show that the intramolecular 8-membered ring N – H … O = C hydrogen bonding energies in the five β-dipeptide structures β-di, β-di-R1, β-di-R2, β-di-R3, and β-di-R4 are -5.50, -5.40, -7.28, -4.94, and -6.84 kcal/mol with BSSE correction, respectively; the intramolecular 12-membered ring N – H … O = C hydrogen bonding energies in the nine β-tripeptide structures β-tri, β-tri-R1, β-tri-R2, β-tri-R3, β-tri-R4, β-tri-R1', β-tri-R2', β-tri-R3' and β-tri-R4' are -10.23, -10.32, -9.53, -10.30, -10.32, -10.55, -10.09, -10.51, and -9.60 kcal/mol with BSSE correction, respectively. Our calculation results further indicate that for the intramolecular 8-membered ring hydrogen bondings, the structures where the orientation of the side chain methyl group is "a–a" have stronger intramolecular hydrogen bondings than those where the orientation of the side chain methyl group is "e–e", while for the intramolecular 12-membered ring hydrogen bondings, the structures where the orientation of the side chain methyl group is "e–e" have stronger intramolecular hydrogen bondings than those where the orientation of the side chain methyl group is "a–a". The method is also applied to estimate the individual intermolecular hydrogen bonding energies in the dimers of amino-acetaldehyde, 2-amino-acetamide, 2-oxo-acetamide, and oxalamide, each dimer having two identical intermolecular hydrogen bonds. According to our method, the individual intermolecular hydrogen bonding energies in the four dimers are calculated to be -1.71, -1.50, -4.67, and -3.22 kcal/mol at the MP2/6-311++G(d,p) level, which are in good agreement with the values of -1.84, -1.72, -4.93, and -3.26 kcal/mol predicted by the supermolecular method.

Streszczenie:
Advanced analytical techniques were utilized to investigate the intermolecular forces in several nanostructured materials. Techniques including, but not limited to, isothermal titration calorimetry (ITC), variable temperature Fourier transform infrared (FTIR) spectroscopy, and ultraviolet-visible (UV-Vis) thermal curves were used to study the fundamental interactions present in various nanomaterials, and to further probe the influence of these interactions on the overall behavior of the material. The areas of focus included self-assembly of surfactant micelles, polycation complexation of DNA, and temperature-dependent hydrogen bonding in polymeric systems. ITC was successfully used to determine the low critical micelle concentration (CMC) for a novel gemini surfactant with limited water solubility. CMCs were measured at decreasing methanol molar fractions (xMeOH) in water and the resulting linear relationship between CMC and methanol concentration was used to mathematically extrapolate to a predicted CMC at xMeOH = 0. Using this technique, the CMC value for the novel gemini surfactant was predicted to be 0.037 ± 0.004 mM. This extrapolation technique was also validated with surfactant standards. ITC was also used to investigate the binding thermodynamics of polyplex formation with polycations and DNA. The imidazolium-containing and trehalose-based polycations were both found to have endothermic, entropically driven binding with DNA, while the adenine-containing polycation exhibited exothermic DNA binding. In addition, ITC was also used to confirm the stoichiometric binding ratio of linear polyethylenimine and DNA polyplexes as determined by a novel NMR method. Dynamic light scattering (DLS) and zeta potential measurements were also performed to determine the size and surface charge of polyplexes. Circular dichroism (CD) and FTIR spectroscopies provided information regarding the structural changes that may occur in the DNA upon complexation with polymers. UV-Vis thermal curves indicated that polyplexes exhibit a greater thermal stability than DNA by itself. Variable temperature FTIR spectroscopy was used to quantitatively compare the hydrogen bonding behavior of multi-walled carbon nanotube (MWCNT)-polyurethane composites. Spectra were collected from 35 to 185 deg C for samples containing various weight percent loadings of MWCNTs with different hydrogen bonding surface functionalities. Peak fitting analysis was performed in the carbonyl-stretching region for each sample, and the hydrogen-bonding index (Rindex) was reported. Rindex values were used to quantitatively compare all of the composite samples in regards to temperature effects, weight percent loadings of MWCNTs, and the different functionalizations. In general, higher weight percent loadings of the MWCNTs resulted in greater Rindex values and increased hydrogen bond dissociation temperatures. In addition, at 5 and 10 wt% loadings the initial Rindex values displayed a trend that tracked well with the increasing hydrogen bonding capacity of the various surface functionalities.

In this work three different approaches to the study of intermolecular interactions are shown. The aim is to further the understanding of specific intermolecular interactions with a view to eventually allowing the prediction and design of crystal structures from the initial molecular building blocks: crystal engineering. All three approaches make use of crystal structural information derived from X-ray and/or neutron diffraction studies. The three approaches are: • Data base approach. Specifically, the study of occurrence of hi- and tri-furcated hydrogen bonds in the Crystallographic Structural Database, and the analysis of the frequency with which they occur and the geometric restrictions of such interactions.• Analysis of a series of compounds, where there are small changes in the molecular structure as the series progresses. The influence of these changes in the molecular structure on the crystal structure is considered. The series studied was the 4-amino- 4'-hydroxydiphenylalkanes as well as some of the corresponding 4-amino-4'- hydroxydiphenylsulphides and -alkylsulphides.• Detailed analysis of individual structures to identify the intermolecular interactions that are influencing the structure. The compounds analysed in this part were 2,4,6- m.s-(4-chlorophenoxy)-l,3,5-triazene co-crystallised with tribromobenzene, triphenylisocyanurate co-crystallised with trinitrobenzene, 4,4'-dinitrotetrapheny 1 methane, 2,3-dichloro-l,4-diethynyl-l,4-dihydroxy-napthalene and, 4,4-diphenyl- 2,5-cyclohexadienone.

Streszczenie:
The implications of chain topology and intermolecular interactions on the electrospinning process were investigated for linear and randomly branched polymers. Empirical correlations were developed based on solution rheological measurements that predict the onset of electrospun fiber formation and average fiber diameter. In particular, for neutral, non-associating polymer solutions, the minimum concentration required for fiber formation was the entanglement concentration (Ce), and uniform, bead-free fibers were formed at 2 to 2.5 Ce. This was attributed to entanglement couplings stabilizing the electrospinning jet and preventing the Raleigh instability. Moreover, the influence of molar mass and degree of branching on electrospun fiber diameter was eliminated when the polymer concentration was normalized with Ce, and the fiber diameter universally scaled with C/Ce to the 2.7 power. Polymers modified with quadruple hydrogen bonding groups were investigated to determine the role of intermolecular interactions on the solution rheological behavior and the electrospinning process. In nonpolar solvents, the hydrogen bonding functionalized polymers displayed significant deviation from the electrospinning behavior for neutral solutions due to the strong intermolecular associations of the multiple hydrogen bonding groups. The predicted electrospinning behavior was recovered when the hydrogen bonding interactions were screened with a polar solvent. Moreover, it was observed that branching and multiple hydrogen bonding afforded significant processing advantages compared to functionalized, linear analogs of equal molar mass. For example, branched chains in the unassociated state possessed a larger Ce compared to the linear chains, which indicated a lower entanglement density of the former. However, in the associated state the linear and branched chains possessed nearly equivalent Ce values, suggesting a similar entanglement density. Thus, the branched polymers displayed significantly lower viscosities in the unassociated state compared to linear polymers, while still retaining sufficient entanglements in the associated state due to the reversible network structure of the multiple hydrogen bond sites. The solution rheological and processing behavior of polyelectrolyte solutions was also investigated to discern the role of electrostatic interactions on electrospun fiber formation. In particular, the polyelectrolyte solutions formed nano-scale electrospun fibers with an average fiber diameter 2 to 3 orders of magnitude smaller than neutral polymer solutions of equivalent viscosity and C/Ce. This was attributed to the very high electrical conductivity of the polyelectrolyte solutions, which imparted a high degree of charge repulsion in the electrospinning jet and increased the extent of plastic stretching in the polymer filament. In fact, the average diameter of the polyelectrolyte fibers under certain conditions was less than 100 nm, which makes them good candidates for protective clothing applications due to their high specific surface area. Moreover, the neutral polymer solution electrospinning behavior was recovered after the addition of NaCl, which screened the electrostatic charge repulsions along the polyelectrolyte main chain. Finally, electrospun, biocompatible phospholipid membranes were produced from solutions of entangled worm-like lecithin micelles. This is the first example of successfully electrospinning low molar mass, amphiphilic compounds into uniform fibers. Electrospinning the phospholipid worm-like micelles into nonwoven fibrous mats will afford direct engineering of bio-functional, high surface area membranes without the use of multiple synthetic steps, complicated electrospinning setups, or post processing surface treatments.

ENGLISH ABSTRACT: This thesis reports an in-depth investigation of the intermolecular interaction motifs in secondary, primary and ammonium carboxylate salts. The investigation was conducted using the Cambridge Structural Database (CSD), together with a systematic steric-specific experimental study. The tendency in the literature has been to analyse organic salt crystal structures in terms of hydrogen bonding patterns, almost ignoring cation-anion interactions. This study focuses on the cation-anion interactions in secondary, primary and ammonium carboxylate salts, which have a direct effect on the formation of specific structural motifs. The ideas of ring-stacking and ring-laddering, which arise from the tendency of cations and anions to arrange themselves so as to maximise electrostatic interactions, have been applied to ammonium carboxylate salts. An extensive survey of organic ammonium carboxylate salt structures in the CSD has been carried out. The structural motifs in ammonium carboxylates were investigated, and a set of predictive rules for the pattern of intermolecular interactions in these salts was developed. Using these results, the formation of ring-stacking or ring-laddering in primary ammonium carboxylate salts can be predicted. The results from the CSD survey are discussed in Chapter 3. An experimental study has been carried out, which complements the results obtained from the CSD survey. The experimental study formed 19 novel ammonium carboxylate salts, of which 2 formed hydrates and 2 co-crystals of salts. The experimental results confirm what was found in the CSD survey, and this is discussed in Chapter 4. This study has found that the principle of ring-stacking and ring-laddering can be applied in a general form to the crystal structures of organic ammonium carboxylate salts. The size of the cation and the anion in these salts has a significant effect on the formation of structural motifs in the solid state. Interactions between cation and anion substituents also play an important role in the formation of particular structural motifs in ammonium carboxylate salts.
AFRIKAANSE OPSOMMING: In hierdie tesis word die intermolekulêre interaksie motiewe in die sekondêre, primêre en ammonium karbosilaat soute in-diepte ondersoek. Die studie is gedoen met behulp van die Cambridge Strukturele Databasis (CSD), saam met ‟n sistematiese steriesspesifieke eksperimentele studie. Die neiging in die literatuur is om organiese sout kristal strukture in terme van waterstofbindings patrone te analiseer sonder om katioon-anioon interaksies in ag te neem. Die studie fokus juis op hierdie katioon-anioon interaksies tussen sekondêre, primêre en ammonium karbosilaat soute wat ‟n direkte effek het op die vorming van spesifieke strukturele motiewe naamlik „ring-stacking‟ en „ring-laddering‟ wat hul oorsprong kry vanaf die neiging van katione en anione om hulself op so ‟n wyse te rangskik sodat die elektrostatiese interaksies ‟n maksimum kan bereik, op die ammonium karboksilaat soute. ‟n Volledige ondersoek van ammonium karboksilaat soute in die CSD is gedoen. Die strukturele motiewe in ammonium karboksilaat is ondersoek, en ‟n stel reels wat die patrone van intermolekulêre interaksies in hierdie soute voorspelis ontwikkel. Hierdie resultate kan gebruik word om die vorming van „ring-stacking‟ en „ring-laddering‟ in primêre ammonium karbosilaat soute te voorspel. Die resultate van die CSD ondersoek word bespreek in Hoofstuk 3. ‟n Eksperimentele studie is uitgevoer en die resultate hiervan komplimenteer die resultate van die CSD ondersoek. In die eksperimentele studie is 19 nuwe ammonium karboksilaat soute gekristaliseer, waarvan 2 hidraat-soute en 2 ko-kristal-van-soute is. Die eksperimentele resultate bevestig die bevindings van die CSD ondersoek, en dit word bespreek in Hoofstuk 4. Hierdie studie het gevind dat die beginsel van „ring-stacking‟ en „ring-laddering‟ kan in „n algemene vorm in die kristal strukture van organiese ammonium karboksilaat soute toegepas word. Die grootte van die katioon en anion in hierdie soute het ‟n beduidende effek op die vorming van strukturele motiewe in die vaste toestand. Interaksie tussen die katioon en anioon substituente speel „n belangrike rol in die vorming van spesifieke motiewe in ammonium karbosilaat soute.

Streszczenie:
A blue shift in the CH stretching vibration of formic acid cyclic dimer of 6.6 ern" (symmetric) and 3 ern" (antisymmetric) is observed by high resolution Raman (symmetric) and infrared (antisymmetric) spectroscopy. This is corroborated by theoretical ab initio calculations where blue shifts in the CH stretching vibration of 12.79 ern" (symmetric) and 10.26 ern" (antisymmetric) are calculated (CP corrected MP2/6-311++G(d,p) level of theory). This is unusual due to the CH bond not playing a direct part in the bonding of the dimer. The electric dipole moment derivative curve with respect to bond length of the CH bond in formic acid is found to be unusual. The equilibrium bond length is on the negative gradient side of the maximum of the dipole, and this has been used to explain interesting behaviour observed, including the blue shift of the CH stretching vibration and how the contribution of electrostatics to the interaction energy can cause a blue shift of the stretching vibration in the spectrum. A mechanism is proposed where the electron density is transferred from the CH bond, through to the OH site where bonding does take place. This in turn causes the CH bond to have increased polarity, and therefore the bond contracts due to this interaction. Several chloroform complexes are investigated, which show either blue shifting or red shifting of the CH stretching vibration. Complexation with dimethyl ether shows an experimental red shift of the CH stretching vibration of chloroform of -1.5 ern", and a theoretical shift of -2.11 crn'. The complex of chloroform with trimethyl amine shows an experimental red shift of the CH stretching vibration of chloroform of -54 ern", and a theoretical prediction of -79.51 ern". Both of these complexes show a 1: 1 stoichiometric equation. The chloroform self dimer shows blue shifts in the CH stretching vibration, calculated to be 2.1 and 8.8 ern", experimental results are currently inconclusive. Morokuma Kitaura energy decomposition has been used to understand the energy contributions to intermolecular bonding. Electrostatic interaction and exchange repulsion have been shown to be the main contributions to bonding, but some unusual cases, for example the CH bond of formic acid cyclic dimer, have shown electrostatics to cause a blue shift. - 3 - A tuneable stimulated Raman photoacoustic spectroscopy (PARS) set up has been further applied to the trace detection of H2' and has achieved a detection limit of 6.69 ppm by volume. A non-dispersive Raman shifter method has also been investigated as a simpler alternative to the tuneable PARS set up and has achieved a less sensitive detection limit of 108 ppm by volume. Methane has also been detected qualitatively via this method, using the Raman shifter as a source of infrared light.

Streszczenie:
This book deals with the electron density distribution in molecules and solids as obtained experimentally by X-ray diffraction. It is a comprehensive treatment of the methods involved, and the interpretation of the experimental results in terms of chemical bonding and intermolecular interactions. Inorganic and organic solids, as well as metals, are covered in the chapters dealing with specific systems. As a whole, this monograph is especially appealing because of its broad interface with numerous disciplines. Accurate X-ray diffraction intensities contain fundamental information on the charge distribution in crystals, which can be compared directly with theoretical results, and used to derive other physical properties, such as electrostatic moments, the electrostatic potential and lattice energies, which are accessible by spectroscopic and thermodynamic measurements. Consequently, the work will be of great interest to a broad range of crystallographers and physical scientists.

The thermodynamics and kinetics of clathrate hydrate formation processes are topics of high scientific interest, especially in the petroleum industry. Researchers have made efforts at understanding the underlying processes that explicate the macroscopic observations from experiments and other research methods of gas hydrate formation. To achieve this, they have employed theories founded upon force related intermolecular interactions. Some of the theories and concepts employed include hydrogen bonding, the Leonard Jones force principle, and steric interactions. This paper gives a brief review of how these intermolecular interaction principles have been understood, and used as tools, in explaining the inaccessible microscopic processes, that characterize clathrate hydrate formation. It touches upon nucleation, growth, and inhibition processes.

This paper describes a time-resolved measurement of thermal property in microscale during reaction process of a polymer by using an infrared (IR) laser. Polymer and gel-like material, so-called macromolecules, have diversity in its structure and intermolecular association, and recent development of measurement and control technique in micro- and nano-scale has open up new possibilities for the property design in the materials, including the control of thermophysical properties. The heat conduction process in macromolecules is affected by the internal structure or intermolecular association of the material. Thus, the intermolecular dynamics of polymer can be reflected in time-resolved information of the thermal conductivity or thermal diffusivity. A measurement system of the thermal diffusivity in time-resolved and non-contact manner based on the forced Rayleigh scattering method (FRSM) has been developed. This system can be applied for a changing process of a wide variety of polymer material because of employing a CO2 laser with the infrared wavelength of 10.6 μm. Also, it is possible to measure micro-scale property. In the present study, the measurement area is set at 500 μm in diameter. By using the IR-FRSM system, an investigation of the relationship between intermolecular dynamics of macromolecules and energy transfer can be conducted through the time-resolved data of the thermal diffusivity. As samples, crosslinking processes of a polysaccharide aqueous solution and an ultraviolet curable polymer are measured; variations in molecular interactions caused by hydrogen and covalent bonding occur, respectively. Time evolution of the measured thermal property from the IR-FRSM system clearly indicates the difference in bonding modes of macromolecules. According to the time-resolved measurement results, the validity of the IR-FRSM for a versatile instrument of intermolecular dynamics of macromolecules is demonstrated.

Abstract Polymer healing, referring to the intermolecular diffusion across the interfaces of thermoplastic tape layers in intimate contact, is one of the important steps in fusion bonding responsible for the development of interlaminar bond strength, and is strongly influenced by the temperature history. In this paper, a model for the healing process under non-isothermal conditions is developed starting from a fundamental formulation of the reptation of polymer chains. Considering the temperature dependence of the reptation time, the bond strength is described as a function of temperature history. Parametric studies and comparison of the model with available models in the literature are presented.

Streszczenie:
In situ infrared vibrational spectroscopy of the electrode/solution interface has established itself as an efficient and informative method for study of the orientation and structure of adsorbed species. The method is growing rapidly in popularity due to is ease in implementation. Very high sensitivities (approximately 10-6 adsorbance) is attained with relatively simple instrumentation and by simple single external specular reflection. A range of related experimental techniques and their application has led to study of problems of wide electrochemical and general interest including: a) The detection and identification in aqueous and non-aqueous solvents of the potential dependent populations of solvent, simple ions, and organic solutes both in the adsorbed state and free in the double layer using a wide range of metallic and non-metallic electrode materials including well-defined single crystal surfaces. b) The investigation of the orientation, surface bonding, and intermolecular interaction of adsorbed species and the effects of electrode potential on these parameters. c) The identification and kinetics of reaction of adsorbed and non-adsorbed reaction intermediates such as radical anions and cations.
