10. RECENT RESEARCH
 In this paper, we propose a new and complete mechanism for dual
fluorescence of methyl salicylate (MS) under different conditions using a
combined experimental (i.e., steady-state absorption and emission
spectra and time-resolved fluorescence spectra) and theoretical (i.e.,
time-dependent density function theory) study. First, our theoretical study
indicates that the barrier height for excited state intramolecular proton
transfer (ESIPT) reaction of ketoB depends on the solvent polarity. In
nonpolar solvents, the ESIPT reaction of ketoB is barrierless; the barrier
height will increase with increasing solvent polarity. Second, we found
that, in alcoholic solvents, intermolecular hydrogen bonding plays a more
important role. The ketoB form of MS can form two hydrogen bonds with
alcoholic solvents; one will facilitate ESIPT and produce the emission
band in the blue region; the other one precludes ESIPT and produces the
emission band in the near-UV region. Our proposed new mechanism can
well explain previous results as well as our new experimental results.
