英文摘要the synthesis and photophysics of two novel 2-(2'-hydroxyphenyl)-benzothiazole (hbt) derivatives are presented. the electron-withdrawing trifluoromethyl (cf3) group in compound 1 facilitates the deprotonation of the phenolic hydroxy group. well-resolved triple fluorescence from the enol, keto, and phenolic anion, which ranges from 350 to 600 nm, was detected for 1 in ethanol, which marks the first time triple fluorescence from an excited-state intramolecular proton transfer (esipt) molecule has been reported. both triphenylamine and cf3 were introduced into derivative 2. intramolecular charge transfer and the "red-edge effect" resulted in the bathochromic shift of dual fluorescence of 2. triple fluorescence was also observed for 2 in ethanol. in mixed acetonitrile and ethanol, pure white-light emission with cie coordinates of (0.33, 0.33) and a quantum yield of 0.25 was achieved for 2. this work provides a new avenue for the rational design of an esipt molecule to achieve white-light generation under mild conditions.
