Abstract

Highly nonlinear chromophores with good thermal stabilities (> 250 °C) are required if organic polymeric materials are to be developed for electro-optical (EO) applications. The synthesis and characterization of highly efficient and thermally stable diphenylamino-substituted thiophene stilbenes (e.g., see Figure) are reported, one of which was used to form a high-EO-coefficient composite with a polyquinoline.
