摘　　要：Static and transient spectroscopic characters of newly synthesized start-like molecules, 1,3,5-tri（10-butyl-3-propenyl-10H-phenothiazine）-benzene （TP3B） and 2,4,6-tri（10-butyl-3-propenyl -10H-phenothiazine）-[1,3,5]triazine （TP3T）, are studied using static, picosecond fluorescence and femtosecond transient absorption spectroscopy. The results show that when the benzene group is in the center, a large conjugation system is formed, while a fast electron-transfer process happens when the center group is triazine.Static and transient spectroscopic characters of newly synthesized start-like molecules, 1,3,5-tri（10-butyl-3-propenyl-10H-phenothiazine）-benzene （TP3B） and 2,4,6-tri（10-butyl-3-propenyl -10H-phenothiazine）-[1,3,5]triazine （TP3T）, are studied using static, picosecond fluorescence and femtosecond transient absorption spectroscopy.
