• reversible addition fragmentation chain transfer (RAFT)
• rod-coil copolymers

A simple and efficient approach for the preparation of rod-coil block copolymers comprising oligo-and polythiophenes blocks together with PMMA or PS blocks is described. The block copolymers were prepared using a two-step procedure. alpha,omega-dicarboxy-terminated oligothiophenes and carboxy terminated poly(3-hexylthiophene) were first prepared. These were then reacted with P(4)S(10) in a second step to generate the alpha,omega-thioester terminated oligothiophenes and poly(3-hexylthiophene)s which were subsequently used in a one-pot reaction as RAFT polymerization agents with methylmethacrylate and styrene. The di- and tri-block copolymers hence obtained were fully characterized, both in solution and as thin films.
