英文摘要 | an excited-state proton transfer (espt) process, induced by both intermolecular and intramolecular hydrogen-bonding interactions, is proposed to account for the fluorescence sensing mechanism of a fluoride chemosensor, phenyl-1h-anthra(1,2-d)imidazole-6,11-dione. the time-dependent density functional theory (td-dft) method has been applied to investigate the different electronic states. the present theoretical study of this chemosensor, as well as its anion and fluoride complex, has been conducted with a view to monitoring its structural and photophysical properties. the proton of the chemosensor can shift to fluoride in the ground state but transfers from the proton donor (nh group) to a proton acceptor (neighboring carbonyl group) in the first singlet excited state. this may explain the observed red shifts in the fluorescence spectra in the relevant fluorescent sensing mechanism.
