Fluorescence Emission Intensity

The photo-induced fluorescence enhancement for a BOPIM derivate, which was found weak or no fluorescence in solvents due to twisted intramolecular charge transfer (TICT) was investigated. The quenching process because of TICT state is substantially removed and fluorescence emission intensity increased remarkably, induced by UV-irradiation. This phenomenon could only found in moderate polar solvent, such as CHCl3, THF and 1, 4-dioxane (DIOX), but not in more polarity solvent, such as CH3CN, CH3OH. It is indicated that the transformation from TICT to ICT state take place easily in moderate polar solvents.
