A new 3-(4,5-dibenzyldithio-1,3-dithiol-2-ylidene)naphthopyranone (3) has been synthesized. The molecular structure was identified and characterized by UV-Vis, 1H NMR, 13C NMR, IR and TOFMS techniques. The electronic spectra, thermostability and fluorescence spectroscopy of 3 were briefly studied. The geometric structure of the product was optimized using Gaussian 03 quantum chemical program package with the method of density functional theory (DFT) at the B3PW91 level. The calculating results are in agreement with the experimental values. The research shows that 3 displays an intramolecular charge-transfer transition and remarkable fluorescence properies which were instructive explorations for pursuing new luminescent materials.

Key words: synthesis, charge transfer, absorption spectra, fluorescent property, density functional theory
