A generic approach to high temperature stable, functionalized polyimides for nonlinear optics has been developed and the resulting polyimides exhibit excellent temporal stability in dipole orientation at elevated temperatures, such as 150degrees}C. Large second harmonic generation coefficients and electro-optic coefficients have been achieved. These polyimides exhibit good solubility in common organic
已经开发出一种用于非线性光学的高温稳定功能化聚酰亚胺的通用方法,所得聚酰亚胺在高温(例如 150°C)下表现出优异的偶极取向时间稳定性。已经实现了大的二次谐波产生系数和电光系数。这些聚酰亚胺在普通有机溶剂中表现出良好的溶解性,并且可以很容易地加工成薄膜。各种非线性光学发色团已被纳入聚酰亚胺主链,这使我们能够系统地研究结构-性能关系。
