Abstract
⺠A series of novel diphenyl sulfone-based bis-pyrazoline derivatives were designed and synthesized. ⺠Their UV-vis absorption and fluorescence emission spectra were investigated. ⺠The relationship of substituents and the optical properties were discussed. ⺠With increasing the solvent polarity, fluorescence emission displayed a red-shift and fluorescence quantum yields decreased. ⺠Fluorescence was quenched when the concentration increased over to 10â5 M.
