Chemical Reactions At Metal Surfaces: Functionalization Strategies And Spectroscopic Characterization, Sydney Legge

Electronic Thesis and Dissertation Repository

Tremendous interest in increasing the control over surface properties has led to high demand for new efficient methods for chemical surface modifications. In this work, several approaches toward surface functionalization are explored, and modified surfaces are subsequently characterized using uniquely suited spectroscopic techniques. In the first part of this thesis, strain-promoted alkyne-azide cycloaddition (SPAAC) reactions are investigated for their potential to precisely tune the surface properties of gold substrates at the monolayer level. The utility of SPAAC reactions in preparing biorecognition interfaces for cell adhesion is then examined. Polarization modulation infrared reflection-absorption spectroscopy is used to characterize adsorbed monolayers and …
