2C12 新規キラルネマティック液晶場でのアセチレン重合

抄録

Recently we synthesized helical polyacetylene in asymmetric reaction field which was prepared by adding a chiraldopant into nematic liquid crystal. Here, 2, 2'-butyl-bridged-1, 1'-binaphthyl derivative were synthesized as new chiral dopants. It was found that the metylene chain-bridged binaphthyl derivatives have a reversed helical twisting power, compared with those of non-bridged binaphthyl derivatives used so far as chkal dopants.
