Abstract

The second order nonlinear optical response of two dipolar thiopheno-quinoid chromophores are calculated using extensive single and double-excitation configuration interaction. The (beta) values are found to be comparable in magnitude to those for the pheno-quinoid systems. The sign of the nonlinear response is, however, found to be positive in these systems, in contrast to the second-order nonlinear optical response of pheno-quinoid structures which are known to be negative.
