    • In a complementary approach, an enantiomericaily pure cationic C 60-bisadduct was utilized to induce a predominantly one-handed helix in a dynamically racemic poly(phenylacetylene) with the opposite negative charges in DMSO-water mixtures through noncovalent bonding interactions, which further resulted in a helical array of the C60-bisadducts with a predominant screw-sense along the polymer chain.

    • 4b,5 The copolymer composition ([2]/[4] = 10.8/89.2 (mol/mol)) was in fair agreement with that in the feed. This clearly indicates that the polymerizability of 2 is almost identical to that of 4 and that the monomer distributions in the copolymers of 2 and 4 may be random, independent of the monomer conversion (see run 7 in Table 1).
