英文摘要Excited-state intermolecular or intramolecular proton transfer (ESIPT) reaction has important potential applications in biological probes. In this paper, the effect of benzo-annelation on intermolecular hydrogen bond and proton transfer reaction of the 2-methyl-3-hydroxy-4(1H)-quinolone (MQ) dye in methanol solvent is investigated by the density functional theory and time-dependent density functional theory approaches. Both the primary structure parameters and infrared vibrational spectra analysis of MQ and its benzo-analogue 2-methyl-3-hydroxy-4(1H)-benzo-quinolone (MBQ) show that the intermolecular hydrogen bond O-1?H2O3 significantly strengthens in the excited state, whereas another intermolecular hydrogen bond O-3?H4O5 weakens slightly. Simulated electron absorption and fluorescence spectra are agreement with the experimental data. The noncovalent interaction analysis displays that the intermolecular hydrogen bonds of MQ are obviously stronger than that of MBQ. Additionally, the energy profile analysis via the proton transfer reaction pathway illustrates that the ESIPT reaction of MBQ is relatively harder than that of MQ. Therefore, the effect of benzo-annelation of the MQ dye weakens the intermolecular hydrogen bond and relatively inhibits the proton transfer reaction.
