Abstract

This contribution reports on the photophysical and photochemical behavior of several ((N,N-dimethylamino) methyl) arenes. Monomer (arene) fluorescence is strongly quenched by efficient intramolecular charge transfer from the amino to the arene group. The properties of the resulting exciplexes vary considerably with the arene moiety, the position of attachment of the amino group and with solvent polarity. All of the compounds investigated show photochemical decomposition by σ(CN) bond cleavage. It is suggested that the CT state is precursor to the dissociative 3σ*(CN) state.
