摘要:

通过重氮耦合和酯化等反应制备了一系列侧向含有酰胺基团的偶氮苯类非线性光学生色团, 并将其与聚合物进行掺杂或通过分子间的侧向氢键作用制备了主客体型及超分子型的电光薄膜材料. 生色团的结构通过核磁共振谱(1H NMR, NMR)、 红外光谱(IR)、 质谱(MS)和元素分析(EA)等进行了表征, 结果表明, 生色团形成了分子间的氢键作用. 通过紫外-可见(UV-Vis) 光谱研究了材料的极化性能. 相比主客体型电光薄膜材料, 由分子间侧向氢键作用形成的超分子型电光薄膜材料无需与聚合物基体材料复合, 更有利于提高材料的生色团含量、 极化取向度及稳定性. 通过Teng-Man简单反射法研究了主客体型和超分子型电光材料的二阶非线性光学性质, 结果表明, 基于分子间侧向氢键作用形成的超分子体系具有更大的电光系数.

Abstract:

A new series of azobenzene nonlinear optical(NLO) chromophores was prepared by diazo coupling and esterification reactions, and the “gest-host” and “supramolecular” NLO materials were also prepared by doping or intermolecular lateral hydrogen bonding interaction. The chemical structures of these chromophores were characterized. The intermolecular lateral hydrogen bonding interaction in these chromophores was confirmed by 1H NMR. The UV-Vis spectra of these NLO materials showed that the chromophore loading, poling efficiency and alignment stability could be greatly improved by the intermolecular lateral hydrogen bonding interaction. The electro-optic(E-O) activities of these materials were also studied. Compared with “gest-host” type, the “supramolecular” type NLO materials based on the intermolecular lateral hydrogen bonding interaction had larger E-O coefficients.

Key words: Second-order nonlinear optics property, Lateral hydrogen bonding, Supramolecule type electrooptic material, Poling efficiency, Azobenzene chromophore
