Coordination polymerization of a conjugated enyne: Synthesis of a novel polyacetylene derivative bearing conjugated double bond moieties
The coordination polymerization of 1-ethynylcyclohexene was carried out using various rhodium catalysts. Polymerization catalyzed with [Rh(norbornadiene)Cl](2)/triethylamine gave a well-defined polyacetylene derivative bearing conjugated double bond moieties, whose UV-vis absorption spectrum has its maximum at 380 nm and cut off at 500 nm.
