Abstract
The fluorescence spectra of N-salicylidene-p-(N,N-dimethylamino)aniline have been investigated in various solvents and three kinds of fluorescence were found; they were that of excited intermediate, exciplex and excited dimer. According to the transient absorption spectra and decay kinetic data of photoproducts of the title compound, it has been found that the photoproducts in cyclohexane are a zwitterion and a mixed dimer formed by a zwitterion and an enol; in acetonitrile the photoproducts are a zwitterion, a mixed dimer formed by a zwitterion and an enol and a dimer formed of zwitterion. Photochromic and luminescence mechanisms of the title compound are discussed as well.
