[Study on the TICT property of phenothiazine and its derivatives].
The radiationless quantum yields ( phi(nr) ) of phenothiazine (PTH). N-phenyl phenothiazine (PHZ). N-(2-pyridine) phenothiazine (PYZ) and model compound p-N, N-dimethylaminobenzonitrile (DMABN)in benzene were measured. The effects of solvents on phi(nr) of DMABN,PHZ,PYZ and PTH were investigated respectively. It was found that phi(nr) of PYZ and DMABN were dependent on the solvent polar parameter (E(T)(30)) . From the results of radiationless quantum yields and combining the state and dynamic fluorescence spectra, it is proved that PYZ as well as DMABN appears TICT property.
