The catalytic activity of the [Rh(cod)Cl] 2 complex (cod cis , cis ‐cyclo‐octa‐1,5‐diene) with respect to the polymerization of ethynylferrocene (EFc) was examined. A good yield (about 80%) of polyethynylferrocene (PEFc) was obtained in benzene by addition of sodium hydroxide as co‐catalyst. PEFc was insoluble in most organic solvents. The conductivity (s̀) of the undoped polymer is about 10 −11 ohm −1 cm −1 ; upon doping PEFc with iodine in tetrahydrofuran the conductivity can be increased to 10‐100 ohm −1 cm −1 . The influence of other doping agents was also examined.
