High-performance, low-voltage organic field-effect transistors using thieno[3,2-b]thiophene and benzothiadiazole co-polymers

Abstract

A series of new linear conjugated polymers incorporating different substituted thieno[3,2-b]thiophenes as donor, acetylene as π-bridge and benzothiadiazole as acceptor units were synthesizedviaPd-catalyzed Sonogashira cross-coupling polymerization.
