Developing Iron Complexes For Electrocatalytic Hydrogen Generation, Benjamin Travis

Undergraduate Honors Theses

Artificial photosynthesis systems convert solar energy into chemical fuels such as hydrogen gas. Photocatalytic hydrogen generation systems have previously been developed, but reliance on expensive metal catalysts limits the viability of these systems. In order for artificial photosynthesis to be used as a large-scale clean energy solution, it is crucial to discover more active and cost-efficient catalysts.

To this end, several novel iron polypyridyl complexes were synthesized using relatively inexpensive reactants. Electrochemical testing revealed that these complexes are active electrocatalysts for the reduction of protons to generate hydrogen gas. Furthermore, a naphthalene-terminated iron polypyridyl complex was found to be an …

Synthesis And In-Vitro Cell Viability/Cytotoxicity Studies Of Novel Pyrrolobenzodiazepine Derivatives, John M. Jarrett

Undergraduate Honors Theses

Pyrrolobenzodiazepines (PBDs) are a group of naturally occurring compounds that were discovered in the cultures of Streptomyces in the 1960s. Some natural PBDs discovered in these cultures, such as anthramycin and sibiromycin, were shown to possess a broad spectrum of anti-tumor activity. Since cancer is still a leading cause of death globally, the development of novel anti-proliferative derivatives of PBDs is essential for human welfare worldwide. Further synthesis and structure-activity relationship (SAR) studies of the parent natural products and their tetracyclic analogs will lead to the discovery of drug candidates. In this work, thirteen PBD analogues were synthesized using no …
