The synthesis of poly(N-vinylcarbazole)-based block copolymers functionalized with rhenium diimine complexes or pendant terpyridine ligands is reported. The copolymers are synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization, and they exhibit interesting morphological properties as a result of the phase separation between different blocks. The rhenium complex polymer block may function as a photosensitizer, while the terpyridine-containing polymer block can be used as the template for nanofabrication by selective deposition of zinc complexes.
