Abstract:
Four compounds (TM-1~4) based on N-(4-trifluoromethylphenyl)phenothiazine-S,S-dioxide and N-[3,5-bis(trifluoromethyl)phenyl]phenothiazine-S,S-dioxide are synthesized by Buchwald-Hartwig cross coupling reaction. The effect of different substituents in acceptors on the electronic, photophysical and electrochemical properties are studied by UV–Vis, fluorescence spectroscopy, cyclic voltammetry curves and theoretical calculations. The energy gaps (ΔEST) between singlet excited states (S1) and triplet excited states (T1) of these compounds decrease by addition of one para-substituted />CF<sub>3</sub> or two meta-substituted <img style=
