摘要：

The optimiztion of second order optical nonliearity requires molecules with a specific degree of ground‐state polarization. In this connection, studies of extended thiophne‐containing compunds with acceptors that gain aromaticity on charge separation, such as the molecule shown, are described. As it also exhibits good therma stability, this compound is a promising candidate for electro‐optic poled polymer applications. (Figure Presented.) Copyright © 1994 Verlag GmbH & Co. KGaA, Weinheim
