Abstract

Abstract: The cis-trans isomerization of stilbene photosensitized by perylene is studied. The photo-sensitization is found involving electron transfer from singlet excited state of perylene to stilbene. Applied magnetic field (1.5?10^-2T) reduces the efficiency of photosensitization, particularly when the reaction is carried out in micellar solution.

Key words: electron transfer photosensitization, magnetic field effect, stilbene, isome-rization reaction, micellar solution
