Optically active polyacetylene: Synthesis and helical conformation of a poly(phenylacetylene) carrying L-alanyl-L-alanine pendants
A phenylacetylene carrying a chiral L-alanine dipeptide moiety has been synthesized, and it has been polymerized by (2,5-norbornadiene)rhodine(I) chloride dimmer ([Rh(nbd)Cl](2)) into a high-molecular weight polymer in a high yield. The polymer chain takes a helical conformation with preferred handedness, which can be tuned by the solvent and temperature.
