EFFECT OF POLYMERIC MATRICES AND TEMPERATURES ON EXCIPLEX EMISSIONS

This paper is concerned with the photochemistry and photophysics of exciplexes (complexes in the excited state) in solutions which are currently under intensive investigation. In polymeric matrices, on the other hand, the scope and limitations of such processes are not well defined. The present study reveals that the emission from exciplexes in polymeric matrices differs considerably from that in fluid solutions of similar polarity. In experiments, the authors used N,N-dimethyl-p-toluidine in order to have a better analogy to the chromophore chemically bonded to the polymer.
