Der volle Inhalt der QuelleThe synthesis and characterization of folding aromatic oligoamides with reduced constraint, ion-pair associations and solvent-mediated folding of aromatic oligoureas, and oligoamides with unique conformational variations involving simple structural inversion are presented in this thesis.
Chapter 1 is a review of the foldamer field defining structural features of peptides that are desired for replication by artificial building blocks. Foldamers are characterized as either peptidomimetic or abiotic based on intrinsic properties of the building blocks utilized. Each section of peptidomimetic and abiotic foldamers demonstrates the systematic design and characterization utilized for each system, including highlights of progressive developments within the field. This leads into the early development of helical aromatic oligoamides, developed by Gong and coworkers, incorporating rotation restricting three-center hydrogen bonds imbedded in the backbone. Overall, providing the relationship between our helical aromatic oligoamides and their place in the foldamer field.
Chapter 2 presents modifications in the design of robust aromatic oligoamides to incorporate reduced hydrogen bonding constraint within the backbone. This increased flexibility was to improve protein-like folding behavior for these previously robust oligoamides. Flexibility was designed by removing aromatic side chains adjacent to the benzene residues allowing only 5-membered ring (two-center) hydrogen bonding to remain. Two variations of oligoamides were synthesized involving alternating constraint consisting of interchanging three- and two-center hydrogen bonding along the aromatic backbone, and reduced constraint with only 2-center hydrogen bonding. Folding potentials are presented utilizing a combination of circular dichroism, 1D/ 2D NMR experiments, thermal denaturation and titration experiments in varying solvent conditions.
Chapter 3 begins with an overview of past aromatic oligourea design and cationic recognition of uncyclized and cyclized aromatic tetraureas. Anionic recognition of halides with ureas observed in literature was confirmed by concentration-dependent 1H-NMR experiments for aromatic urea dimers, similar in structure to elongated oligourea sequences. Anions were also observed to associate with oligourea trimers with similar affinities compared to their iv tetraethylammonium salt counterions, not previously observed for the dimers. Cation binding within the cavity of these trimers was confirmed by 2D NMR experiments. Correlations between 2D NMR spectra and results from concentration-dependent 1H-NMR experiments led to the conclusion of positive cooperative association between anion and cation pairs with oligourea trimer hosts. The conformational preference of longer aromatic oligoureas, incorporating fivemembered hydrogen bonding constraining the urea-linkage, was determined to favor a trans-trans conformation based on urea-linkage bond rotations that were computationally derived in collaboration with Professor Eva Zurek and Daniel Miller. Longer oligoureas were confirmed to also to bind tetraethyl- and tetrabutylammonium cations by 2D NMR experiments. Folding and chain-length dependence of these longer oligoureas were characterized by circular dichroism and 1H-NMR, confirming solvent-dependent folding and aggregation. Finally an aromatic oligourea 9mer was confirmed to favor a helical structure stabilized by dimethylformamide.
Chapter 4 presents two aromatic oligoamides with a simple inversion between their αβ and βα-amino acid spacers which caused the individual conformational identity to differ dramatically, preventing these complementary strands to associate. A qualitative examination compared differences in structural properties by 1H-NMR concentration-dependent, titrationdependent and temperature-dependent experiments. It was concluded that the oligoamide involving the αβ spacer preferred to fold upon itself, generating a stable β-turn which was confirmed by 2D NMR. The oligoamide incorporating a βα spacer self-dimerized with significant conformational interconversion, requiring the oligoamide to be examined at cryogenic temperatures to derive a specific conformation. In collaboration with Professor Eva Zurek and Daniel Miller, conformations derived from NOEs observed by 2D NMR experiments were examined computationally. A favored model paired with atomic distances calculated from optimized NOEs concluded the refinement of a specific conformation regarding this oligoamide.

Der volle Inhalt der QuelleWe have studied the pyrolysis of aromatic combustion intermediates using an array of detection techniques. The molecules investigated include cyclic aromatic molecules with hydrocarbon substituents (ethylbenzene, n-propylbenzene, isopropylbenzene, and styrene), oxygen-containing substituents (anisole and phenol), resonance stabilized radicals (benzyl radical and tropyl radical) and phenyl radical. At the exit of a resistively heated micro-reactor (1 mm inner diameter, 3 cm long), the pyrolysis fragments are detected using photoionization mass spectrometry (PIMS), matrix isolation vibrational spectroscopy, microwave spectroscopy, tunable VUV synchrotron-based PIMS, and tabletop VUV PIMS with photoelectron photoion coincidence spectroscopy (PEPICO). This array of detection methods allows for the identification of all possible fragments including metastables, radicals, and atoms. The findings allow for detailed mechanistic information regarding which pathways are active at different pyrolysis temperatures and can also be used to help identify products and individual isomers that are formed during the gas-phase thermal decomposition of aromatic systems. By providing direct experimental pyrolysis data, models for fuel decomposition and soot formation can be improved to help understand current combustion systems and eventually aid in the design of superior fuel sources in the near future.

Der volle Inhalt der QuelleMore than two-thirds of all enzyme substrates and cofactors are anionic, emphasizing the essential role that anions play in biological processes. Moreover, anions can have detrimental effects on the environment by causing ground water contamination when anions such as perchlorate, phosphate and nitrate develop in intolerable levels. Owing to the prevalent nature of anions, traditional strategies employed to target anions--including hydrogen bonding, metal ion coordination and electrostatic interactions--have been extensively studied. An alternative approach to anion binding would complement the powerful array of existing techniques. Recently, in the supramolecular chemistry community, new insight has been cast on how anions attractively interact with electron-deficient arenes, suggesting that aromatic rings are a viable anion binding strategy to balance existing methods. Chapter I provides a historical perspective of anions interacting with electron- deficient arenes. This outlook has its origins in the late 1800s with the discovery of colored charge-transfer complexes between donor and acceptor molecules and continues with the progression of the field leading up to the recent supramolecular fascination. Chapter II represents our initial efforts at measuring anion/arene interactions in solution. In particular, sulfonamide based hydrogen bonding receptors were developed with pendant aromatic rings to test the strength of anion/arene interactions in solution. Complementary computational chemistry and crystallography were utilized to supplement the solution studies. Chapter III describes our quantum calculations and crystallographic efforts at using only electron-deficient arenes to bind halides. A Cambridge Structure Database survey supports our emphasis of understanding multiple anion/arene interactions. Chapter IV illustrates how tripodal anion receptors can be developed to bind anions using only electron-deficient aromatic rings. Furthermore, subtle changes in anion binding geometries are observed with isomeric receptors and corroborated with Density Functional Theory calculations. Chapter V is dedicated to the preparation of electron-deficient anion receptors that are conformationally stabilized by hydrogen bonds. Chapter VI is committed to using our knowledge of anion binding to study a series of ethynyl-pyridine sulfonamides capable of hydrogen bonding to small molecules and anions. In conclusion, Chapter VII is a summary and future prospective for the field of anion/arene interactions. This dissertation includes previously published and co-authored material.
