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.
