A facile one-step synthetic method to functionalize regioregular polythiophene is described (see Figure). End-group functionalization leads to a number of new uses for these polymers including end-group-driven self-assembly onto surfaces and into conducting polymer networks, and their use as building blocks for the synthesis of block copolymers.
