Communication: Organometallic polymers with a transition‐metal ion incorporated into a conjugated chain are of potential interest as conductors and semiconductors. The structural criteria which are known to enhance conductivity, such as strong ligand–metal interactions, co‐planarity of aromatic ligands, and high molecular weight, are met by the new material shown in the Figure.

More favorable electroactivity (in the reductive electrocatalytic coupling of aryl halides) is observed for adsorbed polymeric nickel phosphine complexes than with their covalently anchored monomeric nickel analogues. Syntheses of the relevant ligands are described and methodology for formation of polyvinylbenzyl chloride bearing pendant bisphosphinobenzene groups and polymers with bisphosphinobenzene incorporated into the backbone is discussed. The electrochemical activities of these ligands and their coordinated nickel complexes provide useful probes for the characterization of the chemically modified electrode surfaces.
