Abstract
By the measurements of the solvent and temperature effects of the fluo rescence emission spectra and lifetime of N-phenyl phenothiazine (PHZ) and N-(2-pyridine) phenothiazine (PYZ), the existence of strongly twi sted intramolecular charge transfer (TICT) state in PYZ emission spect ra is proved. The exciplex formed by PHZ, PYZ and dimethyl terephthala te (DMTP) is investigated, and moreover, the transient absorption spec tra of positive and negative ions as the results of the dissociation o f the exciplex in the polar solvents is observed through.the flash pho tolysis.
