Main-chain nonlinear optical polymers based on novel chromophores with special structures presented good solubility in most of the organic solvents. Polymers PE-1 and PE-2 attained the thermal decomposition temperatures of 305 and 223 °C and glass transition temperatures of 113 and 108 °C, and exhibited only negligible decay in the SHG signal baked at 85 °C over hundreds of hours, respectively. The SHG coefficients of poled films from polymers PE-1 and PE-2 were 26.3 and 35.8 pm/V, respectively. These results indicated that this class of polymers can be used in the preparation of organic electro-optic devices.
基于具有特殊结构的新型生色团的主链非线性光学聚合物在大多数有机溶剂中具有良好的溶解性。聚合物 PE-1 和 PE-2 的热分解温度分别为 305°C 和 223°C，玻璃化转变温度分别为 113°C 和 108°C，在 85°C 下烘烤数百小时后，其倍频信号仅略有衰减。从聚合物 PE-1 和 PE-2 制得的极化膜的倍频系数分别为 26.3 和 35.8 pm/V。这些结果表明，这类聚合物可用于制备有机电光器件。
