Photooxidation of electron-rich compounds (donor) sensitized by 9,10-dicyanoanthracene (DCA, acceptor) gives evidence for the effect of solvent polarity on the photochemical reaction mechanism.The chemical outcome can be connected with the fluorescence data.The formation of O2^. and (1)O2 proceeds from a charge transfer complex between the donor and the acceptor upon excitation.
