Poly[p-{L-(-)-menthoxycarbonyl}phenylacetylene]s prepared by [Rh(norbornadiene)Cl]2 as a polymerization catalyst exhibited a much higher [alpha]D20 (= - 605 ) than that(= - 68.8 ) of the monomer and a very high molar ellipticity(more than 10(4)) at the pi-pi* region in the CD spectrum: A chiral helical conformation of the main chain in solution is suggested. The solid membrane of this polymer showed enantioselective permeability (54%ee) for DL-tryptophan.
