Abstract: The photophysical behavior of titled compound has been studied. Results show that the fluorescence spectra and the fluorescence quantum yields depend strongly on the polarity and the viscosity of solvents. The rate constants of the radiation and ra-diationless decay processes of the excited compound were calculated. A comparative study has been carried out between compounds which possess binding and unbinding structures respectively.
