Looking at biopolymers like nucleic acids having various vital functions such as molecular recognition and catalytic ability associated with their well defined helical structure, it is obvious that the synthesis of well-organized one-handed helical polymers is an attractive and important area of research. Toshiki Aoki and co-workers have synthesized a series of substituted phenylacetylenes having various linear or branched alkyl groups with a chiral catalytic system. The influence of these alkyl groups on solubility, molecular weight, chiroptical properties, and crystallinity of the resulting polymers are discussed. A membrane fabricated form one of these polymers exhibits enantioselective permeability which is the first example to confirm directly the effect of a one-handed helical main chain on the chiral recognition ability.
