中文摘要 | diphenyl-o-methoxyphenylmethyl methacrylate was polymerized with several organolithium complexes of chiral ligand such as (-)-sparteine (sp) and (s,s)-(+)-2,3-dimethoxy-1,4-bis(dimethylamino)butane (ddb). (+)-ddb was effective in preparing a polymer of high optical rotation, whereas (-)-sp only gave oligomers with low optical rotation for the repulsive hindrance between the bulky ester group and the rigid ligand. the optical rotation of the polymer decreased rapidly to a constant value due to the propeller-propeller transition, which has been demonstrated by h-1 n.m.r. and circular dichroic spectra. |
