Thiol-Ene Click Chemistry for Solid State Triplet-Triplet Annihilation Upconversion and Parts-Per-Billion Pyrophosphate Sensing in Artificial Seawater
… networks fabricated using thiol-ene click photopolymerization. The advancement of triplet-triplet annihilation based upconversion (TTA-UC) in emerging technologies necessitates the development of solid-state systems that are readily accessible and broadly applicable. We demonstrate that …

Synthesis and Characterization of Polymeric Materials as Sequestrants for Biological Applications
… as these materials are not widely explored for post-polymerization modification, particularly with biologically relevant molecules such as glycans and cationic compounds. While we observed partial functionalization of the polymer backbone at longer reaction times, we demonstrated that the …

Synthesis, Properties, and Biology of Advanced H2S-Releasing Materials
… polymers. Copolymers prepared using RAFT polymerization could be functionalized with SATOs with conversions > 99%, and these polymers released H2S on a similar timescale to our small molecule donors, confirming the viability of SATO formation as a post-polymerization modification strategy. …

Design and synthesis of mechanoresponsive materials and multivalent polymer-peptide conjugates
… including specially designed monomers and post polymerization functionalization. This thesis focuses on two examples of intrinsic functionalization. First, mechanophores are incorporated into polymers and impart function when materials are subjected to mechanical force. Second, multivalent …

Synthesis of Highly Ordered Polymer Nanostructures Based on Polyphenylene Vinylenes (PPVs)
… side chain regioregularity were prepared. Before polymerization into the polymeric structures, the physical properties of the individual oligomers was probed. As expected, the solution phase cyclic voltammetry (CV) and absorption spectra of each oligomer were found to be essential identical. In …

Synthesis and Characterization of Glycomaterials for Antibacterial Applications
Every year, millions of people contract antibiotic-resistant bacterial infections, and tens of thousands die from infection-related complications in the United States alone. Bacterial infections are one of the leading causes of death worldwide, especially in healthcare institutes such as hospitals …
