For excited-state intramolecular proton transfer (ESIPT) fluorophores, the intramolecular hydrogen bond strength has decisive influence on their photophysical properties. Herein, a series of 2-(2-hydroxyphenyl)benzothiazole (HBT) derivatives as new ESIPT fluorophores are synthesized through Sonogash...
