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 article, we formed a β-cyclodextrinchromophore inclusion compound by embedding a dumb-bell shape chromophore in a β-cyclodextrin. Compared to hyperbranched chromophores, this inclusion compound could create a 360° steric hindrance and pull the distance between molecules. Then this inclusion compound could prevent chromophore aggregation and minimize the interactions which hamper higher nonlinear optical activity. The method of the refractive index for electro-optic materials which can determine the degree of chromophore aggregation in polymers was first proposed and confirmed in this work. These properties have provided a great promise in the fabrication of EO materials and devices.
