基于分子间侧向氢键作用的电光材料制备及性能
Synthesis and Characterization of Electro-optic Materials Based on Intermolecular Lateral Hydrogen Bonding†
摘要
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 1 H NMR. The UV-Vis spectra of these NLO materials showed that the chromophore loading, pol-ing 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.关键词
