摘要：

合成了新型的含有偶氮和噻吩环的二阶非线性光学功能分子, 用红外光谱、紫外光谱、核磁共振和质谱确定了其结构; 制备了含有该功能分子的两种交联型聚氨酯聚合物薄膜, 当测量波长为1 064 nm时, 用Marker条纹法测得的二阶非线性光学系数d₃₃值分别为80.6 pm/V(发色团的数密度为0.91×10²⁰ Molecules/cm³)和20.1 pm/V(发色团的数密度为2.21×10²⁰ Molecules/cm³); 聚合物Ⅱ的取向热稳定性达到了152 ℃.

Abstract:

A novel second-order NLO azo-chromophore containing thiophene conjugated bridge and TCF acceptor was synthesized and characterized by means of IR, UV, MS and ¹H NMR. Two types of crosslinking polyurethane containing this chromophore were prepared, in which TEA and BPAN acted as the crosslinking agents, respectively. Second harmonic coefficient d₃₃ values for the two polymers were measured by Marker-fringe method at 1 064 nm, they were 20.1 pm/V(chromophore number density is 2.21×10²⁰ molecules/cm³) and 80.6 pm/V(chromophore number density is 0.91×10²⁰ molecules/cm³), respectively. Polymer Ⅱ showed a thermal stability of 152 ℃, which was 71 ℃ higher than polymer Ⅰ.
