Dynamics and Stabilization of Materials Possessing High Energy Content
Abstract
The objectives of the research supported by this AFOSR grant were to create new knowledge concerning the nature and behavior of high energy content materials adsorbed at the liquid liquid, liquid-solid, and the solid-gas interfaces. The strategy employed was to use photochemical reactions and photophysical parameters as probes to characterize the structure and dynamics of high energy species. The reactions of radical pairs produced by photochemical excitation of ketones and the electron transfer process between a metal complex and an electron acceptor were employed as general photochemical probes of a range of interfacial regions. The techniques used were a battery of time resolved spectroscopic methods including optical absorption, optical emission, nuclear magnetic resonance and electron spin resonance. The objects achieved were the development of a framework which now allows both the chemistry of high energy species adsorbed at interfaces to be controlled and manipulated and the structure and dynamics of the interfacial region to be better understood.
