Abstract:

AbstractCovalent organic frameworks (COFs) are distinguished from other organic polymers by their crystallinity1–3, but it remains challenging to obtain robust, highly crystalline COFs because the framework-forming reactions are poorly reversible4,5. More reversible chemistry can improve crystallinity6–9, but this typically yields COFs with poor physicochemical stability and limited application scope5. Here we report a general and scalable protocol to prepare robust, highly crystalline imine COFs, based on an unexpected framework reconstruction. In contrast to standard approaches in which monomers are initially randomly aligned, our method involves the pre-organization of monomers using a reversible and removable covalent tether, followed by confined polymerization. This reconstruction route produces reconstructed COFs with greatly enhanced crystallinity and much higher porosity by means of a simple vacuum-free synthetic procedure. The increased crystallinity in the reconstructed COFs improves charge carrier transport, leading to sacrificial photocatalytic hydrogen evolution rates of up to 27.98 mmol h−1 g−1. This nanoconfinement-assisted reconstruction strategy is a step towards programming function in organic materials through atomistic structural control.

Abstract:

The search for supramolecular promising porous crystalline materials with diverse applications such as gas storage, catalysis, chemo-sensing, energy storage, and optoelectronic have led to the design and construction of Covalent Organic Frameworks (COFs). COFs are a class of porous crystalline polymers that allow the precise integration of organic building blocks and linkage motifs to create predesigned skeletons and nano-porous materials. In this review article, a historic overview of the chemistry of COFs, survey of the advances in topology design and synthetic reactions, basic design principles that govern the formation of COFs as porous crystalline polymers as well as common synthetic procedures and characterization techniques are discussed. Furthermore some challenges associate with the synthesis of COFs are highlighted. We hope that this review will help researchers, industrialists and academics in no mean feat.

Abstract:

Covalent Organic Frameworks (COFs) are a novel class of highly stable, purely organic crystalline frameworks made of molecular building blocks. For example, the condensation of boronic acids with appropriate polyols in principle allows the design of precisely controllable structures since their chemical and physical properties can be easily tuned through the selection of the building blocks. The young research field of COFs has attracted scientists due to their extraordinary and versatile properties, however, strategies to control the topology and the properties of the backbone as well as the inner surface are still not well established. With support of Prof. Knochel and his group, who contributed numerous new organic COF linkers, this thesis aims to extend the functionalization strategies for the design of Covalent Organic Frameworks. Investigation of the structural modification and the associated change in physical and chemical properties should lead to progress regarding the applicability of these materials. Employing the concept of reticular chemistry in combination with High Throughput Synthesis Techniques, the formation of a very large Covalent Organic Framework BTP-COF with 4 nm open pores was successfully carried out. The solvothermal co-condensation of 1,3,5-benzenetris(4-phenylboronic acid) (BTPA) and 2,3,6,7-tetrahydroxy-9,10-dimethyl-anthracene (THDMA) was carried out using microwave irradiation instead of conventional synthesis in an oven, thus synthesis time of BTP-COF was reduced from initially 72 h to 5 min. Extending the open pore diameter of a crystalline material to 4 nm, in combination with the resulting high accessible surface area of 2000 m2/g offers great potential to exploit organic reactions in the pores and enables the incorporation of large functional guests, such as polymers or dyes. Bearing these results in mind the scope of functionalization possibilities was expanded from the geometric extension to the chemical modification of the inner surface of COFs. Decorating the organic building blocks with small functional active groups, such as methyl-, -methoxy- and hydroxy- allowed for the successful synthesis of several organic frameworks. Chemical and physical properties of the backbone and the inner surface can be precisely tailored by chemical modification of the building blocks. In order to investigate post-synthetic modification strategies, the methyl- and hydroxy-groups were used as reaction anchor points to covalently attach molecules after framework formation. The co-condensation of benzene-1,3,5-triyltriboronic acid (BTBA) and the 9,10-dimethyl-anthracene-2,3,6,7-tetraol (DMAT) succeeded in the formation of AT-COF-Me. In a radical bromination reaction the methyl groups of an anthracene linker were successfully brominated giving AT-COF-Br without degrading the crystalline framework of AT-COF-Me. The formation of the resulting benzylic bromine was monitored with IR spectroscopy and solid state NMR, respectively. Elemental analysis results correspond to the bromination of half the -CH3 groups. Reaction of (2',5'-dihydroxy-[1,1':4',1''-terphenyl]-4,4''-diyl)diboronic acid (HTDBA) and 2,3,6,7,10,11-hexahydroxytri-phenylene (HHTP) The terphenyl-based hydroxyl substituted T-COF-OH, formed by (2',5'-dihydroxy-[1,1':4',1''-terphenyl]-4,4''-diyl)diboronic acid (HTDBA) and 2,3,6,7,10,11-hexahydroxytri-phenylene (HHTP), was tested in several nucleophilic substitution reactions. Esterification of the –OH group was achieved with either acetylchloride or in a Steglich type reaction with 4-pentynoic acid. X-ray diffraction analysis after the post-synthetic modification shows that the crystallinity of the framework was preserved. This indicates that T-COF-OH is compatible with the reaction conditions. The detection of the newly formed ester moieties in IR and in solid state NMR spectra proves the successful post-synthetic esterification of the –OH groups. Another approach to tailor functionality in COFs is to assemble monomers with distinct properties in COF synthesis. Modification of the backbone of the framework was realized with two heterocyclic building blocks. Benzothiadiazole (BTD) and thienothiophene (TT) monomers are known as building blocks of semiconducting polymers. These molecules were equipped with boronic acid or boronate ester moieties in para position. The linkers were then used in co-condensation reactions with HHTP. The synthesis of BTD-COF was carried out in a two step microwave synthesis procedure: first the pinacolboronate 4,7-Bis(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)benzo[c][1,2,5]thiadiazole (BTDA) was cleaved with HCl, in a second step addition of HHTP resulted in the crystalline product in only 60 min. TT-COF was synthesized in a conventional co-condensation reaction of thieno[3,2-b]thiophene-2,5-diyldiboronic acid (TTBA) with HHTP; the black TT-COF showed aborbance over the whole spectrum of the visible light. Upon irradiation with light the system showed significant photoconductivity. The 3 nm pores of the hole-transporting TT-COF offer enough space to incorporate large fullerene-based electron-transporting materials such as PCBM. This inclusion leads to a significant quenching of the luminescence of TT-COF, indicating light-induced charge transfer at the interface of these two materials. The oriented growth of thin films of porous COF-10, a product of the condensation of 4,4’-biphenyldiboronic acid(BPBA) and HHTP, and TT-COF on self-assembled monomer (SAM)-functionalized gold surfaces is shown. Films grown on boronic acid terminated SAMs result in a parallel orientation of the pores along the substrate. Scanning electron microscopy was used to investigate the morphology of the films. Homogenous films with thicknesses of around 150 nm and a total coverage of the substrates were obtained. In summary, several functionalization strategies are shown to control or tune the topology and properties of Covalent Organic Frameworks. Tuning the topology and functionality to large open pore systems or intrinsic semiconductivity allows incorporation of large functional molecules and study the host-guest interactions. The post-synthetic modification of COFs offers a synthetic pathway to integrate organic functionalities, which cannot be synthesized directly by co-condensation. These strategies provide the means necessary for a precise control of the pore environment and design a porous material for specific applications. A facile and rapid method to produce thin oriented COF films will pave the way for this material to fabricate technological devices, such as photovoltaic devices, sensors of OFETs.

Materiais bidimensionais apresentam possibilidades de funcionalização que os tornam versáteis para diversas aplicações, tais como em dispositivos eletrônicos. A presença de poros nesses materiais pode trazer novas funções, como adsorção de gases, liberação controlada de fármacos e catálise. Os covalent organic frameworks (COFs) são uma nova classe de materiais orgânicos porosos cristalinos que têm recebido destaque em química reticular. O objetivo dessa dissertação é apresentar a síntese e caracterização de quatro novos COFs baseados em carbazóis, que constitui uma classe de compostos utilizada na obtenção de polímeros condutores. O bloco de montagem principal utilizado foi o 3,6-diamino-9H-carbazol e as fontes de aldeído foram triformilfloroglucinol, triformilfenol, 1,3,5-tri(4-formilfenil)benzeno e triformilbenzeno para a síntese do RIO2, RIO3, RIO5 e RIO6, respectivamente. RIO2 e RIO3 apresentaram-se sob a forma ceto enamina e imina, respectivamente, além de pouca cristalinidade e baixa área específica. Através de cálculos baseados na Teoria do Funcional da Densidade (DFT), foi verificado que esses COFs apresentam suas folhas deslocadas e rotacionadas devido às interações eletrostáticas e para minimizar os momentos de dipolo das ligações N-H dos carbazóis. RIO5 e RIO6 também se apresentaram pouco cristalinos e com áreas específicas baixas. Apesar desses resultados, esses materiais ainda podem ser aplicados em eletrônica orgânica por apresentarem estrutura química compatível com tal aplicação.
Two-dimensional materials have functionalization possibilities that make them versatile for various applications such as in electronic devices. The presence of pores in these materials can give new features to them, such as gas adsorption, drug delivery and catalysis. The covalent organic frameworks (COFs) are a new class of crystalline porous organic materials that have been prominent in reticular chemistry. The purpose of this work is to present the synthesis and characterization of four new COFs based on carbazoles, which are a class of compounds used to obtain conductive polymers. The main building block used was 3,6-diamine-9H-carbazole with the aldehyde sources were triformylphloroglucinol, triformylphenol, 1,3,5-tri(4 formylphenyl)benzene and triformylbenzene to obtain RIO2, RIO3, RIO5 and RIO6, respectively. RIO2 and RIO3 are in keto-enamine and imine form, respectively, as well as have low crystallinity and low specific area. Calculus based on Density Functional Theory (DFT) found that these COFs present their sheets displaced and rotated due to electrostatic interactions and to minimize the dipole moments of the N-H bonds of carbazoles. In an attempt to avoid the absence of pores, RIO5 and RIO6 materials were synthesized, however these COFs also performed poorly crystalline and with low specific areas. Despite these results, these materials can also be applied in organic electronics by presenting chemical structure compatible with such application.

Abstract:

The two main subjects of this thesis are the realization of supramolecular self-assembled monolayers at surfaces and the formation of surface-supported two-dimensional covalent organic frameworks. Both topics, albeit different, yield long-range ordered open-pore networks with quite different stabilities, depending on the strength and type of bonds holding them together. The surface of choice is mainly graphite, which is considered an inert substrate. Graphite yields pristine clean, very large and flat surfaces when cleaved, facilitating the observation in real space of the molecular networks adsorbed on these surfaces by means of the Scanning Tunneling Microscope (STM). STM is the main experimental technique used here. It was used to image mostly at the liquid-solid interface under ambient conditions. Using a large tricarboxylic acid adsorbate, long-range order supramolecular self-assembled monolayers were obtained. These monolayers are formed via a delicate interaction balance between adsorbates, substrate, and solvent molecules. Weak van der Waal forces mediate the adsorbate-substrate interaction; hydrogen bonds, the adsorbate-adsorbate interaction. Also, depending on the solvent used and the concentration of adsorbates dissolved in it, different polymorphs are found on the substrate. To understand the nucleation and growth mechanism that give rise to the different self-assembled monolayers, thermodynamical considerations are used. Enthalpic and entropic contributions are evaluated for several of the polymorphs found, explaining their occurance on the basis of the Gibbs free energy per unit area. However, even if this work sheds some light on supramolecular self-assembly, adding also that much research has been done in this field, it is still very difficult to know a priori how adsorbates will behave on a substrate. Thus predictions of which patterns will ultimately arise are hampered. To realize structures that are more stable than those formed via supramolecular self-assembly, several strategies have been proposed. Covalent bond formation is one of them, yielding strong and lightweight structures by using organic molecules composed primarily of light elements. The strength of covalent bonds ranges from strong to very strong, when compared to van der Waals and hydrogen bonds. This characteristic makes correction of possible structural errors difficult to almost impossible. However, when molecules with suitable functional groups are allowed to react under reversible conditions, error correction of covalent bonds becomes feasible, yielding regular structures with the energetically most favorable configurations. In this thesis, this is exemplified with the small 1,4-benzenediboronic acid molecules, yielding monolayers composed of very regular, long-range ordered covalent organic frameworks on graphite. Thermal stability is probed by exposing the structures to relatively high temperatures for prolonged times under atmospheric conditions. Further experiments with larger para-diboronic acids, under similar reversible conditions, yield the expected isotopological regular frameworks with larger unit cell parameters. This demonstrates the proof of principle for the formation of two-dimensional covalent organic frameworks. These two main topics, supramolecular self-assembly and covalent bond formation on surfaces, constitute the basis of this thesis. It is organized as follows: A first part deals with the theoretical background of the main analytical instruments used in this work. Then, the thermodynamics of supramolecular self-assembly is presented, along with the studies of the different polymorphs found using a large tricarboxylic acid as building block. The final part deals with the formation of two-dimensional, long-range ordered covalent organic frameworks, made from organic molecules composed only of light elements. This work show that these last mentioned networks exhibit higher thermal stabilities when compared to self-assembled monolayers held together mainly by strong hydrogen bonds. The viability of larger heteromeric isotopological networks is also explored.

Abstract:

In this work, A new type of organic material, Covalent Organic Frameworks (COF), was successfully demonstrated its functionality for pulsing the solid-state laser. This was based on π-bonding delocalization within the SA. ProPh-PyTA-COF exhibits versatile optical nonlinear absorption. Two saturable absorption behavior with the situation intensity of 92MW/cm2 and 1kW/cm2 were observed. Besides the first pulsed Q-switched all-solid-state laser using COFs as an absorber, the evolution of laser performance as pump power was also characterized and discussed.

Abstract:

Metal-organic frameworks (MOFs) have recently attracted enormous interest over the past few years due to their potential applications in energy storage and gas separation. However, there have been few reports on MOFs for adsorption cooling applications. Adsorption cooling technology is an established alternative to mechanical vapor compression refrigeration systems. Adsorption cooling is an excellent alternative in industrial environments where waste heat is available. Applications also include hybrid systems, refrigeration, powerplant dry cooling, cryogenics, vehicular systems and building HVAC. Adsorption based cooling and refrigeration systems have several advantages including few moving parts and negligible power consumption. Key disadvantages include large thermal mass, bulkiness, complex controls, and low COP (0.2–0.5). We explored the use of metal organic frameworks that have very high mass loading and relatively low heats of adsorption, with certain combinations of refrigerants to demonstrate a new type of highly efficient adsorption chiller. An adsorption chiller based on MOFs suggests that a thermally-driven COP>1 may be possible with these materials, which would represent a fundamental breakthrough in performance of adsorption chiller technology. Computational fluid dynamics combined with a system level lumped-parameter model have been used to project size and performance for chillers with a cooling capacity ranging from a few kW to several thousand kW. In addition, a cost model has been developed to project manufactured cost of entire systems. These systems rely on stacked micro/mini-scale architectures to enhance heat and mass transfer. Presented herein are computational and experimental results for hydrophyilic MOFs, fluorophilic MOFs and also flourophilic Covalent-organic frameworks (COFs).

Abstract:

Crystalline particles known as Metal Organic Frameworks (MOF’s) are known for their large surface area and high adsorption and storage capacity for CO2 gas. Electrospun nanofibers are considered as ideal substrates for synthesizing the MOF particles on the fiber surface. In this project, Polyacrylonitrile (PAN) and a Cu-based MOF known as HKUST-1 were selected as substrate fibers and adsorbent particles respectively. A precursor solution of PAN polymer hybridized with HKUST-1 particles dissolved in Dimehtylformamide (DMF) is used as the primary component solution for electrospinning. SEM images of the electrospun fibers showed small MOF particles formation into the fiber structure. A secondary solvothermal process of MOF particles growing on the fibers was then executed to increase the amount of MOF particles for effectual gas adsorption. The secondary process consists of multiple growth cycles and SEM images showed uniform distribution of porous MOF particles of 2–3μm in size on the fiber surface. EDS report of the fiber confirmed the presence of MOF particles through identification of characteristic Copper elemental peaks of HKUST-1. Thermogravitmetric analysis (TGA) of HKUST-1 doped PAN fiber displayed 32% of total weight loss between 180°C and 350°C thus proving the as-synthesized MOF particles are thermally stable within the mentioned temperature range. A comparative IR spectroscopic result between the gas-treated and gas-untreated fiber samples showed the presence of characteristic peak in the vicinity of 2300 and 2400cm−1 which corroborates the assertion of adsorption of CO2 on the system. Further step involved is to investigate the gas adsorption capacity of the filter system in an experimental test bench. Non-dispersive Infrared (NDIR) CO2 sensors will be used at the gas inlet and outlet parts to measure the concentration of CO2 and determine the amount of gas uptake by the filter system.
