摘要： 利用六亚甲基二异氰酸酯的缩二脲与对硝基偶氮苯甘油单醚的电场极化交联反应合成交联型聚合物非线性光学材料。采用变温红外光谱、DSC、紫外可见吸收光谱研究交联反应时间对非线性生色基团的取向及松弛的影响。

关键词: 非线性光学交联聚合物, 对硝基偶氮苯甘油单醚, 缩二脲

Abstract: The crosslinking reaction of glycidyl monoether of 4-[(p-nitrophenyl)azo] phenol with biuret of hexamethylene diisocyanate has been carried out and investigated by DSC and FTIR techniques.A fully crosslinked nonlinear optical polymer was obtained in a short time, which has a good transparency and maximum absorption wavelength shorter than 400nm.The uniform films formed by spin coating of the THF solution onto transparent substrates were precured for 30 min at 85℃ before corona poling.The orientation and stability of the films were studied by UV-vis spectrum measurement.The orientation of the film decreased to 40% of the original in 4 days after poling for 1.5h at 85℃.However,no relaxation of the poled film was observed in 4 days after poling and crosslinking for 1h at 140℃.

Key words: rosslinked nonlinear optical polymer, glycidyl monoether, biuret
