摘要：

A new thermal-resistant second-order nonlinear optical film has been prepared by in situ poling and sol-gel processing of 1,4-phenylene bis(4-trimethoxylsilylethylbenzoate) (PMSE) and Disperse Red 1 (DR1). The monomer, PMSE, was synthesized by Pt-catalyzed hydrosilylation reaction followed by alcoholysis reaction. The chromophore DR1 was embedded in the crosslinked organosilicon polymeric matrix. The film was characterized by FTIR, differential scanning calorimeter (DSC), and X-ray diffraction (XRD). The elemental analysis shows the DR1 content of the poled film to be about 11 wt%. The second-order harmonic generation (SHG) coefficient (d(33)) of the film is 16.7 pm/v and its thermal stability studies demonstrate that the onset of d(33) decay is about 130 degreesC.
