英文摘要the dynamics of the excited-state intramolecular proton-transfer (esipt) reaction of 10-hydroxybenzo-quinoline (hbq) in different solvents, have been investigated based on the time-dependent density functional theory (td-dft) in detail. upon excitation, the intramolecular hydrogen bond between the hydroxyl and phenanthrene functionality is significantly strengthened in the s-1 state, which can be used as a reasonable tendency for facilitating the esipt process. in addition, the calculated vertical excitation energies in the so state and s-1 state reproduce the experimental uv-vis absorbance and fluorescence emission spectra well. through calculating the fluorescence spectra of the hbq chromophore, two outcomes for this chromophore were found in the s-1 state, which demonstrates that the esipt process occurs. the potential energy curves have been calculated to account for the mechanism of the proton-transfer process in the excited-state. as a result, the barrierless esipt process can occur in the s-1 state with proton transfer from the o atom to the n atom. and maybe the esipt process is easier in methanol solvent due to the higher potential energy difference.
