    A series of new thiophene-bridged chromophores based on the powerful heterocyclic acceptor 3-(dicyanomethylene)-2,3-dihydrobenzothiophene-1,1-dioxide has been synthesized; the dependence of the linear and second-order nonlinear optical properties and thermal stability of these species upon the donor group and the bridging group have been studied. In addition, the synthesis of a related new acceptor, not containing the fused benzene ring, is described and a chromophore based upon this acceptor is studied.

    Abstract Both the linear and nonlinear optical properties of our newly designed high temperature electrooptic chromophores are discussed. In addition to the charge separated mechanism for the new chromophores, isomer effects are equally important in determining the optical properties of the new class.

    Abstract In order to be useful for electro-optic devices, nonlinear optical chromophores must be thermally stable, highly transparent, and have large hyperpolarizabilities. Although these qualities are to some extent mutually exclusive, a small group of chromophores has been prepared that meets the various criteria for applicability.
