Paper Abstract

We report results of recent measurements of excited state decay kinetics in molecules which are commonly used as commercial polymer photostabilizers. Discussion centers on molecules in the 2-(2'-hydroxypheny1)-benzotriazole and 2-hydroxybenzophenone classes. Determination of room temperature fluorescence decay, transient absorption and ground state absorption recovery kinetics are presented. In addition, low temperature spectra and variable temperature fluorescence decay kinetics are also presented. Solvent effects on the spectra and kinetics give considerable insight into the radiationless processes that occur in these systems.
