Summary In a coisotactic copolymer of allylbenzene with (R)-3,7-dimethyl-1-octene(optical purity 95%), the phenyl chromophore shows appreciable dichroic bands. This indicates that the presence of a methylene group between phenyl and backbone does not exclude the asymmetric perturbation by the former. Molecular models and CD calculations suggest that the aromatic units can assume two different situations which cancel CD contribution by exciton dipole-dipole interactions between side chain phenyl groups.
