摘要/Abstract

摘要： 制备了一种新型的发色团分子,实际是由普通发色团分子与β-环糊精形成的超分子包合物.其中的普通发色团分子被设计为哑铃型,并且哑铃形的一边在形成包合物后再完成,使形成的超分子包合物不发生解包合.包合物中β-环糊精对发色团分子的保护可以完全阻止发色团分子的聚集,减弱了材料中发色团分子间的静电相互作用.这种利用超分子包合物对发色团分子的修饰方法可以提高极化过程的效率,从而增加材料的电光活性。

Abstract: In the second order nonlinear(NLO) optics,interchromophore electrostatic interactions have been suggested as a major challenge of the poor efficiency in the poling induced polar order.In this essay,we formed a β-cyclodextrin(βCD)-chromophore inclusion compound by embedding a βCD in a dumb-bell shape chromophore.This inclusion compound could prevent chromophore aggregation and minimize the interactions which hamper higher nonlinear optical activity.

Key words: electro-optical materials, NLO chromophores, β-cyclodextrin, inclusion compounds
