Novel Self-Assembly Of Fullerene-Based Dyads, Ashley D. Anderson

Theses and Dissertations

Eventual depletion and environmental toxicity of natural non-renewable energy resources are two issues pushing research toward alternative energy resources. Nature’s process of renewable, unlimited, clean energy production is photosynthesis and porphyrins are a critical component due to their ability to undergo photoinduced electron transfer. This property also makes porphyrins excellent candidates for applications such as solar cells, water splitting, and optical sensing. Researchers have previously tethered porphyrins to fullerene (C60), an excellent electron acceptor, to mimic the reaction centers in photosynthesis. Photoinduced electron transfer in these donor-acceptor dyads has been investigated with particular focus on factors such as the donor, …

Hypervalent Iodine(Iii) Compounds With (Pseudo)Halide And Tetrazole Ligands In The Synthesis Of Functional Polymers, Rajesh Kumar

Chemistry Theses and Dissertations

The organic compounds of iodine(III) with the general formula ArIL₂ (Ar = aryl, L = (pseudo) halides) degrade homolytically upon irradiation or heating to the corresponding monovalent iodine compound (ArI) and the radicals L^• . If the latter contains a functional group, they can be used to initiate the polymerization of vinyl monomers to afford chain end-functionalized linear polymers. When "conventional" monovinyl monomers are copolymerized with di- or multivinyl monomers (crosslinkers) in the presence of relatively high concentrations of rapidly decomposing ArIL₂ compounds, highly branched polymers are formed that contain multiple chain-end functionalities derived from the radicals …

Arts & Sciences Graduate Student Theses and Dissertations

ABSTRACT OF THE DISSERTATIONOxidative C–C and C–Heteroatom Reactivity of High-Valent Nickel ComplexesbySofia M. SmithDoctor of Philosophy in ChemistryWashington University in St. Louis, 2019Professor Liviu M. Mirica, ChairProfessor Kevin D. Moeller, Co-ChairNickel catalysts are commonly used for cross-coupling reactions such as Negishi, Kumada and Suzuki couplings. While Ni(0), Ni(I), and Ni(II) intermediates are most relevant in these transformations, Ni(III) and Ni(IV) species have also been recently proposed to play a role in catalysis. The formation of C–C and C–heteroatom bonds plays a fundamental role in organic transformations, and today cross-coupling reactions are one of the most powerful tools for the construction …

Synthesis Of A Protein Based Photocatalytic Hydrogen Production System, Alexander M. Brown

Honors Program Theses and Projects

Anthropogenic climate change is one of the most pressing challenges facing humans today. It is scientifically established that the production of copious amounts of greenhouse gases such as carbon dioxide (CO2) is the primarycause of global warming. Many of these greenhouse gases are produced from the combustion of carbon-based fuels and researchers are investigating promising alternative fuel sources such as hydrogen gas. Hydrogen gas is a clean burning fuel that stores a significant amount of chemical potential energy. The goal of this project was to synthesize a protein based photocatalytic hydrogen production system and to characterize the effects of modifications …

Synthesis Of Novel Reiii And Rev Metallointercalator Complexes For Use As Dna Damage Probes, Eli Schwartz

Honors Program Theses and Projects

Cancer is a disease that affects millions around the globe. Treatments such as radiation and chemotherapy are often used to treat cancerous tumors, but are not 100% effective in curing the patient. Alternatively, some research groups have proposed the use of metallointercalators, metal complexes consisting of a rhodium, ruthenium, or iridium metal center with bidentate supporting ligands such as bipyridine and phenanthroline, or tridentate ligands such as terpyridine. The complexes also contain a bidentate intercalating group such as dipyridophenazine. These complexes possess the ability to directly bind to DNA through intercalation between the stacks of DNA base pairs, giving them …

Implementation Of Computational Chemistry As Part Of The Physical Chemistry Curriculum, Erica Hess

Honors Program Theses and Projects

Physical chemistry is a sub-discipline of chemistry that focuses on the study of matter at the molecular and atomic level. Since physical chemistry provides foundational knowledge necessary to explain concepts ranging from atomic to molecular structure, chemical reactions and dynamics, to spectroscopy properties of chemical and biochemical systems, it has deeper connections to all other sub-fields of chemistry. Therefore, it is imperative for undergraduate students within chemical science baccalaureate degree programs have a comprehensive understanding of physical chemistry concepts. However, many students taking physical chemistry at an undergraduate level often cannot see its inherent connections to other chemistry sub-disciplines. This …

Molecular Machines: Synthesis, Modeling, And Applications, Syd Kotar

Student Scholar Symposium Abstracts and Posters

While some of the smallest, most useful machines known to science are the biological molecules that keep living organisms alive, there is a growing advancement of the creation of artificial molecules that have the same function and are more efficient. Molecular machines were invented in 1983 when scientists in France created a machine formed of two interlinked molecular rings. In 2016, the Nobel prize in chemistry was awarded to Feringa, Stoddart, and Sauvage who finally documented molecular machines and put them into energy‐filled states in which their movements could be controlled. From this, molecular machines became known as a group …

Unravel Allostery Mechanism Through Molecular Dynamic Simulations With Machine Learning Approaches, Hongyu Zhou

Chemistry Theses and Dissertations

Allostery is referred to as protein function changes due to external perturbations, and ubiquitous in the living cells. Investigation of the allosteric mechanism is essential for developing drugs or assisting protein engineering. Recently, the population shift model has been proposed to explain the allosteric mechanism. This model emphasizes the importance of conformational distribution in the allostery. In the past several years, I have been continuously working on developing computational methods to explore and quantify protein allostery mechanism. By fully utilizing protein simulation results, several machine learning related methods have been applied to protein systems to investigate the underlying conformational changes …

Synthesis And Analysis Of 6-Acetyl-1,2,3,4-Tetrahydropyridine, A Major Contributor To ‘Mousy’ Off-Flavor In Sour And Wild Beers, Liesel Krout

Thinking Matters Symposium Archive

Unexpected tastes can negatively impact consumer experience in the beer industry. One such taste, a ‘mousy’ off-flavor, is diminishing the quality of sour and wild beers throughout the brewing community. The unpleasant flavor is a result of the combined presence of three organic compounds: 6-acetyl-1,2,3,4-tetrahydropyridine (ATHP), 2-acetyl-1-pyrroline, and 2-ethyl-3,4,5,6-tetrahydropyridine. Because of its unpredictable nature, brewers must wait for the compound to disappear before distribution, costing them valuable time and revenue. The factors responsible for formation, reasons for persistence, and degradation timelines of the compounds were unknown. A method for quantification was therefore necessary to determine those characteristics, and such quantification …

Interfacial Ligand Dynamics And Chemistry On Highly Curved Nanoparticle Surfaces: A Plasmon-Enhanced Spectroscopic Study, Esteban Villarreal

Theses and Dissertations

The dynamic interactions between capping ligands and nanoparticle surfaces play a critical role in guiding shape-controlled nanocrystalline growth, imparting unique physical and chemical properties to the nanoparticles. It has been well established that nanoparticles within the size regime of sub 5 nm possess unique heterogeneous catalytic properties, while sub wavelength metallic nanoparticles exhibit tunable plasmonic activity, when these properties are integrated into a single nanoparticle, it presents a significant opportunity to monitor, in real time, the molecular transformations associated with interfacial interactions at the nanoparticle surface. Using plasmon-enhanced Raman scattering as an ultrasensitive spectroscopic tool combining molecular fingerprinting with time …

Studying Carbon Dioxide Solvent Properties By Microwave Spectroscopic Investigations Of Vinyl Fluoride/Carbon Dioxide Clusters And Developing New Approaches To Decode Rotational Spectra, Prashansa Kannangara

Masters Theses

Supercritical carbon dioxide (sc-C0₂) is an excellent green solvent, but its properties are not thoroughly understood. For example, fluorinated compounds have higher than expected solubility in sc-C0₂. Microwave spectroscopy is one way to learn more about sc-C0₂ because it can be used to determine detailed structures of small clusters of molecules. The purpose of this investigation was to study weak hydrogen bonding interactions in complexes of fluorinated ethylene (solute) with carbon dioxide (C0₂, solvent). Investigations on dimers with one C0₂ molecule and fluorinated ethylene were carried out previously and found two different …
