Spectrochemical Characterization of Chemically Modified Surfaces

Abstract

The applications of surface immobilized chemical functional groups on various substrates have been steadily growing in industry, technology and pure sciences. Silylation is only one mechanism of immobilization, but one which is widely employed. The purpose of these investigations was to determine the effect, if any, of bonding organofunctional groups to siliceous surfaces upon the reaction properties of the functionality. In part, these properties were characterized by the use of a variety of chemical investigations. Any general conclusions necessarily oversimplify the results. However, it is frequently observed that the chemistry of the groups investigated does not deviate greatly from a comparable functional group or compound in solution. Therefore, the utilization of spectroscopic techniques commonly used in solution phase studies is suggested in order to elucidate subtle differences between bound and solution phase functionalities.
