Photoconductive polymers and copolymers of N‐(2‐propynyl) carbazole and N‐(2‐propynyl)phenothiazine

Homopolymers of N‐(2‐propynyl)carbazole, its copolymers with acetylene, and the homopolymer of N‐(2‐propynyl)phenothiazine were prepared using Ti(OBu)4/AIEt3 as the catalyst. The homopolymer of the carbazole derivative was also prepared by its metathetic polymerization catalyzed with the system WOCl4/Ph4Sn. Homopolymers of both monomers and the copolymer of N‐(2‐propynyl)carbazole with a small quantity of acetylene are photoconductive.
