中文摘要 | diphenyl-o-tolylmethyl methacrylate (dptma) was synthesized and polymerized using initiators of organolithium complexes with (+) - (2s,3s) -dimethoxy-1,4-bis(dimethylamino) butane (ddb) and (-) -sparteine (sp) as the chiral ligands. ddb was suitable for its complex effective to prepare optically active poly(diphenyl-o-tolylmethyl methacrylate) (pdptma) with one-handed helical conformation, whereas only low-molecular weight polymer was formed when sp was used as ligand due to the repulsive hindrance between the triarylmethyl group and the ligand. a new mutarotation, propeller-propeller transition, was observed for pdptma from the optical rotation curves and cd spectra in thf solution. the equivalent period of pdptma was estimated to be 14 angstrom based on the x-ray diffraction.
