Exploration of palladium-catalyzed reactions for the synthesis of conjugated polymers

摘要

Abstract: Conjugated polymers are of great interest due to their unique structure, interesting physical properties, and potential applications in electronic or opto-electronic devices. Recently, the synthesis of soluble and processable conjugated polymers with different functionalities has become an active research area. We have been exploring palladium-catalyzed reactions (the Stille and the Heck reactions) for preparing functionalized, conjugated polymers. These palladium catalyzed reactions have the advantage of mild reaction conditions and high yields. Different types of conjugated polymers with different properties and applications, such as liquid crystalline conjugated polymers, photoactive metalloporphyrin-containing polymers, and conjugated photorefractive polymers have been synthesized. !11
