Summary Polymerization reactions of η5-cyclopentadienyl)bis(triphenylphosphine)cobalt complex (2) and diyne monomers (3a-3c) were examined to obtain novel organometallic polymers bearing metallacyclopentadiene moieties in the main chain. When the polymerization reaction of 2 with 4,4′-bis(phenylethynyl)biphenyl (3a) was carried out in toluene at 50°C for 3days, an organometallic polymer having cobaltacyclopentadiene in the main chain was obtained quantitatively. The structure of the resulting polymer was confirmed by 1H-, 13C-NMR, IR, and UV spectra. The number-average molecular weight of the obtained polymer was evaluated as 9,600 (GPC, on the basis of polystyrene).
