PHOTOCHEMICAL AND PHOTOPHYSICAL STUDIES OF ORGANIZED ASSEMBLIES - INTERACTION OF OILS, LONG-CHAIN ALCOHOLS, AND SURFACTANTS FORMING MICRO-EMULSIONS

Abstract

The conditions necessary for forming a microemulsion system with sodium lauryl sulfate, pentanol, dodecane. and water have been established. This system was then used to influence photophysical reactions of molecules solubilized in the microemulsion aggregates. The sizes of the microemulsion aggregates were also determined by a photophysical method and by utilizing a Poisson distribution of reactants in the aggregates. Comments on the nature of the aggregate were obtained from the fluorescence spectra of pyrene carboxaldehyde which resides in the surface and pyrene which resides in the microemulsion interior. It was concluded from studies with the latter probe that pyrene samples a large fra..
