Abstract
Abstract2,4,5-trimethoxybenzylidene propanedinitrile (TMPN) was synthesized by Knoevenagel condensation. Structure of the TMPN was conformed by the elemental analysis and EI-MS, FT-IR, 1H-NMR, 13C-NMR spectroscopy. Absorbance and emission spectrum of the TMPN was studied in different solvent provide that TMPN is good absorbent and emission red shift in absorbance and emission spectra as polarity of the solvents increase. Photophysical properties including, oscillator strength, extinction coefficient, transition dipole moment, stokes shift and fluorescence quantum yield were investigated in order to investigate the physicochemical behaviors of TMPN. Dye undergoes solubilization in different micelles and may be used as a probe to determine the critical micelle concentration (CMC) of SDS and CTAB.
