摘要: 对硝基氧化偶氮苯缩水甘油醚(4)经酸碱开环反应合成得对硝基氧化偶氮苯甘油单醚(5).DSC和偏光显微镜结果表明这两种低分子化合物都能形成液晶相.将(5)与六亚甲基二异氰酸酯的缩二脲进行电场极化交联反应,合成了交联型非线性光学聚合物,用变温FTIR和DSC研究了交联反应过程,利用紫外可见吸收光谱研究了膜极化交联前后的取向及取向稳定性.

Abstract: The synthesis of glycerin monoether of4-[(p-nitrophenyl)azoxy]phenol whichcan form liquid crystalline phases is reported.The crosslinking reaction of glycerin mo-noether of 4-[(p-nitrophenyl)azoxy]phenol by biuret of hexamethylene diisocyanate hasbeen studied by DSC and FTIR spectra. The orientation and stability of a poled andcrosslinked polymer have been investigated by UV-Vis spectra. The orientation relaxationwas not observed in 100 hours for the poled and crosslinked polymer after poling andcrosslinking for 1h at 150℃.
