Abstract

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
