Abstract

AbstractN‐Vinyl‐1,2,4‐triazole (NVTri), which is a nonconjugated N‐vinyl monomer having a basic aromatic heterocycle, was polymerized by reversible addition–fragmentation chain transfer (RAFT) polymerization. With the xanthate‐type chain transfer agent (CTA), reasonable control of the polymerization of NVTri was confirmed by the formation of the relatively low polydispersity products, linear increase in the molecular weight with the conversion, feasibility to control molecular weight, and chain extension experiment. Chain extension from poly(NVTri) to N‐vinyl carbazole (NVC) could be well controlled under suitable conditions and provided novel amphiphilic block copolymers. We investigated assembled structures and basic optoelectronic properties of the block copolymers.
