Problem to Be Solved: to provide a chromophore having a far superior nonlinear optical activity to conventional chromophores and to provide a nonlinear optical element comprising said chromophore.
Solution: a chromophore comprising a donor structure D, a π-conjugated bridge structure B, and an acceptor structure A, the donor structure D comprising an aryl group substituted with a substituted oxy group; and a nonlinear optical element comprising said chromophore.
问题要解决的是:提供一种具有比传统色团更优越的非线性光学活性的色团,并提供包括该色团的非线性光学元件。解决方案是:一种包括给体结构D、π-共轭桥结构B和受体结构A的色团,其中给体结构D包括一个被取代氧基取代的芳基;以及包括该色团的非线性光学元件。
