高T_g交联型二阶非线性光学聚合物的合成

Synthesis of Crosslinked Second Order Nonlinear Optical Polymers with High T_g

合成了双羟基双氨基偶氮苯化合物，将其分别与六亚甲基二异氰酸酯的缩二脲和２，４－甲苯二异氰酸酯进行交联反应合成了两种交联型二阶非线性光学聚合物．利用ＦＴＩＲ光谱和ＤＳＣ对交联反应过程和交联聚合物的玻璃化转变温度进行了研究．采用ＵＶ－Ｖｉｓ吸收光谱对极化交联反应前后膜的取向及取向稳定性进行了研究．

Synthesis and characterization of a diamino dihydroxyl azo compound were reported.The crosslinking reaction process of the diamino dihydroxyl azo compound with the biuret of hexamethylene diisocyanate was studied by FTIR.The glass transition temperatures of crosslinked polymers were measured by DSC.The orientation and oriented stability of crosslinked and poled polymers were studied by UV-Vis spectra.
