displays the combination of favorable characteristics: the high value of the first hyperpolarizability, the small HOMO-LUMO energy gap, the blue shift of the absorption maximum relative to the chromophores with other divinylhetaryl or polyene π-bridges and ultrahigh thermal stability. This chromophore may be considered as a perfect candidate for the development of effective electro-optic materials.
已经设计并合成了属于新型的具有二乙烯基苯基喹喔啉部分的推挽生色团的四个生色团。系统地研究了结构-属性关系;发现构象对生色团的值的第一超极化性的影响是无关紧要的。具有TCF受体和7-二甲基苯胺基乙烯基基团的基于喹喔啉的生色团显示出以下有利特征的组合:第一超极化率的高值,较小的HOMO-LUMO能隙,相对于具有其他二乙烯基杂芳基或多烯π桥和超高的热稳定性。该发色团可以被认为是开发有效电光材料的理想选择。
