Abstract
Novel optically active dendronized polymer bearing biphenyl moiety, poly (R)-(+)-2-{4¢-[3, 4, 5- tridodecyloxy benzyloxy]} biphenyloxy propyl methacrylate, has been successfully synthesized. The chemical structures of intermediates and dendronized monomer were confirmed by 1 H NMR, and the chemical structure of the polymer was studied by 1 H NMR and GPC. The optical activity of intermediates, monomer and polymer was investigated by polarization apparatus. Furthermore, the phase structure and transition behavior of the polymer were studied using DSC, PLM and 1D WAXD. The results show that the synthesized chiral intermediates, monomer and the corresponding polymer all exhibit optical activity, and the polymer forms columnar nematic (FN) phase.
