Abstract

Merocyanine - p-toluenesulufonic acid complex was investigated for the crystal structure and the optical properties. The molecules are crystallized in the space group P1 so that the crystal exhibits a large optical nonlinearity . The second order nonlinear optical coefficient d11 measured by means of the Maker Fringe ifiethod is 314pm/V as a pristine data and 500pm/V after the correction of scattering and is greater than d11 of 2-inethyl-4-nitroaniline.
