of tetrahydroquinolinyl chromophore is 65% and 110% larger than that of either the diethylaminophenyl or triarylaminophenyl chromophores, respectively. The doped film containing the tetrahydroquinolinyl chromophore showed an r33 value of 126 pm/V at the concentration of 25 wt% which is much higher than the electro-optic activity of the diethylaminophenyl derived chromophore (39 pm/V) and six times
合成了一种基于N-(4-二丁基氨基苯基)四氢喹啉基供体的新型生色团,与基于二乙氨基苯基或三芳基氨基苯基供体的传统生色团进行比较。循环伏安法测量表明,新发色团的能隙比结构上相关的发色团小得多。密度泛函理论计算表明,四氢喹啉基生色团的分子二次超极化率(μβ)值分别比二乙基氨基苯基或三芳基氨基苯基生色团的大65%和110%。包含四氢喹啉基生色团的掺杂膜的r 33浓度为25 wt%时的126 pm / V值,远高于二乙氨基苯基衍生的发色团(39 pm / V)的电光活性,是传统三芳基氨基苯基发色团(19 pm / V)的六倍)。四氢喹啉基生色团具有比通常使用的烷基生色团更高的热稳定性(其起始分解温度高于280°C)。
