A new conjugated polymer carrying organometallic pendant groups, poly[4‐(ferrocenylethynyl)phenylacetylene], has been prepared. [Rh(nbd)(OCH 3 )] 2 as a catalyst (nbd = norbornadiene) provides a mixture of an insoluble polymer (yield 71%) free of C≡CH groups and soluble oligomers (yield 22%, MW ca. 1 100). WOCl 4 /2Me 4 Sn as a catalyst provides almost exclusively a polymer (yield 60%, M w = 32·10 3 ) containing a small amount of C≡CH groups that is soluble in aromatic and low‐polarity solvents. Its solubility, however, decreases upon storage in the solid state, probably due to a subsequent crosslinking. The 13 C NMR, IR, UV‐vis and Raman spectra of the monomer and polymers are reported.
