Optically active carbazole vinyl

Optically-active vinyl carbazole derivatives can be polymerized cationically to yield polymers whose optical rotation depends upon the initiator system employed. In contrast cationic polymerization of a series of 2-phenylvinylalkyl thioethers produced polymers of optical rotations identical to those of the corresponding mode compounds. ... 

The synthetic approach to optically active polymers based on the copolymerization of prochiral carbazole containing monomers with easily available optically active vinyl or vinylidenic comonomers is by far the most convenient route to a large variety of optically active polymers. Accordingly, N-vinylcarbazole and spaced-carbazole containing vinyl monomers 11-14 have been copolymerized with different optically active monomers 15-20.
