| Abstract: | A novel soluble π-conjugated polymer, poly(3-octanoylpyrrole-2,5-diyl)-p-nitrobenzylidene](POPNBE), was synthesized by a five-step reaction. As a result of introducing a long aeyl to pyrrole at 3-position, the polymer can be easily solved in polar solvents and be processed into films. The chemical structures of the intermediates and POPNBE were characterized by FTIR, 1H NMR, and UV-Vis-NIR spectrometries.The absorption band in the range of 400-600 nm in the UV-Vis-NIR spectrum is due to the π-π* band gap transition. The optical band gap of POPNBE obtained from the optical absorption is about 1.72eV. The resonant third-order nonlinear optical property of POPNBE at 532 nm was studied by using the degenerate fourwave mixing (DFWM) technique. The resonant third-order nonlinear optical susceptibility of POPNBE is about 3.42×10-8 esu. |
