采用后功能化的方法合成了两种含有砜基吲哚二阶非线性光学发色团侧基的聚硅氧烷分子,通过核磁、红外、紫外-可见、示差扫描量热分析等手段对所得的聚合物进行了表征.此合成方法简便易行,易于产物的分离提纯,为二阶非线性光学材料的合成提供了一种新方法.通过二次谐波产生(SHG)方法测得该聚合物的二阶非线性光学系数d33值分别为21和17 pm/V.

A new synthetic strategy was developed to prepare polysiloxanes with indole-based chromophore side chains, in which sulfonyl groups act as the acceptor groups. Molecular structural characterization for the polymers was presented by 1H NMR, IR and UV-vis spectra and differential scanning calorimetry (DSC). This synthetic method is simple, and the purification is easy. The poled film of 2 and 3 reveals a resonant d33 value of 21 and 17 pm/V respectively by second harmonic generation (SHG) measurements.

Key words: post functionalization, synthesis, indole, sulfonyl group, second2order optical nonlinearity
