Poling Behavior of Anisotropic Refractive Index in a Two-Dimensional Charge-Transfer Carbazole

摘要

Poling behavior of anisotropy in refractive indexof a two-dimensional (2-D) charge-transfer (CT) molecularsystem was investigated by means of m-line method. It was foundthat a dinitro-substituted carbazole with 2-D CT character showssmaller anisotropy and smaller change in refractive index due toorientation relaxation compared with its 1-D CT counterpart,consistent with theoretical prediction.
