Synthetic container molecules that emulate biological structures and feature well-defined nanocavities have attracted tremendous interest among supramolecular chemists due to their promising potentials in ion recognition, catalysis, and chemical sensing. Our laboratory has developed a new class of container molecules, namely, metal-organic supercontainers (MOSCs), which feature both endo and exo cavities suitable for binding guest molecules. The overarching theme of this thesis was to use synthetic manipulations to modify the chemical structure and enhance the functional application of MOSCs in two specific areas, anion binding and chemical sensing. For the application of anion binding, we have designed and synthesized a …

Honors Thesis
Increases in the selling of illicit goods warrant a subsequent need for even more sophisticated methods to prevent counterfeit products from being sold. Surface-enhanced Raman spectroscopy (SERS) has the potential to be a powerful tool to thwart counterfeiters because the unique security tags fabricated with this method are difficult to reproduce without knowing the “secret” recipes used in their preparation. In this work, gold nanostars are used as SERS active substrates since their branched structure allows for strong coupling between the light and plasmonic nanoparticles. As a result, Raman signals of trace amount of chemicals can be easily detected. The …
