The oxidative electrochemistry of the cofacially joined phthalocyanine polymer [Si(Pc)O]n to yield molecular metals/conductive polymers of the type {[Si(Pc)O]Xy}n is studied by a combination of X-ray diffractometric and spectroscopic techniques. Electrochemical methodology includes controlled-potential coulometry and electrochemical potential spectroscopy (ECPS) applied to rapidly stirred slurries or to microcompactions of the solid polymer. From the standpoint of electrically conductive polymers, this study illustrates the great sensitivity of electrochemical phenomena to polymer chain architecture (subunit packing, connectivity, geometry, electronic structure) and counterion structure. From the standpoint of molecular metals, the {[Si-(Pc)O]Xy}n systems represent the only system to date where wide tunability in band filling and counterion identity is possible.
