As reversible fluorescent probes, HTP-1 and HTP-2 have favourable applications for the detection of Zn2+ H2S. Herein, impact solvent on excited-state intramolecular proton transfer (ESIPT) was comprehensively investigated. The obtained geometric parameters infrared (IR) vibrational analysis associated with hydrogen bond (IHB) indicated that strength IHB weakened in excited state. Moreover, structural torsion almost no ICT behaviour ESIPT process did not occur HTP-1. Nevertheless, when 7-nitro-1,2,3-benzoxadiazole (NBD) group replaced H atom, enhanced after photoexcitation, which inhibited twisting tetraphenylethylene, thereby opening channel. Notably, hole-electron frontier molecular orbitals revealed charge decoupling effect reason fluorescence quenching HTP-2. Furthermore, potential energy curves (PECs) more inclined to polar solvents than nonpolar solvents. With a decrease polarity, it conducive process. Our study systematically presents different mechanisms two probe molecules regulated by providing new insights into design development novel probes.
