摘要

Rhodium-catalyzed asymmetric polymerization of achiral arylacetylenes giving polyacetylenes took place in good yields with helix sense selectivity, which was realized by use of a C-2-symmetric tetrafluorobenzobarrelene as a chiral diene ligand. The helical chirality of the polymer is kinetically controlled by the chirality of the diene ligand.
