Abstract:In this work,a new kind of 1,3,5-triaryl-2-pyrazoline compound has been synthesized.Their photophysical behavior including solvent polarity and acid-base effects onthe fluorescence spectra was investigated. Results indicated that this compound not onlypossesses strong solvatochromic effect but also can be used as an acid-base indicator in non-aqueous solvents.Results also proved in further that a competition of two mechanisms of intramolecular charge transfer was existed indeed in the excited molecule of substitutedtriaryl pyrazolines.
Keywords:1  3  5-triaryl-2-pyrazoline  photoinduced charge transfer  non-aqueousacid-base indicator  fluorescence quantum yield
