MICELLAR INDUCED SIMULTANEOUS ENHANCEMENT OF FLUORESCENCE AND THERMAL LENSING

Micelles have been found to simultaneously enhance the fluorescence and thermal lens of solubilized substrates. From the studies of effects of various types of micelles on the fluorescence and thermal lens signals of the anthracene derivatives, it was found that the enhancement depends on the type of micelles and the structure of the substrate. Highest enhancement was achieved when there were strong interactions between them. For instance, the enhancement in the fluorescence and thermal lens of the 11-(9-anthroyloxy)undecanoic acid, whose long hydrocarbon tail renders strong interaction with micelles, specifically nonionic micelles, is about 5.5 and 3.7 times more than that for anthracene.
