Abstract

The cofacially joined metallomacrocyclic polymer [Si(Pc)O]_n (Pc = phthalocyaninato) can be reversibly oxidized electrochemically as a slurry to yield a "molecular metal". As monitored by controlled potential coulometry, X-ray powder diffraction, infrared spectroscopy, specular reflectance spectroscopy, and thermoelectric power, the stoichiometry of the resulting {[Si(Pc)O](BF₄)_y}_n polymers can be continuously varied from y = 0.00 to 0.50. This broad, incremental tuning of the band filling (the first time for a molecular metal) is accompanied by a continuous evolution of the optical and charge transport properties from those of a semiconductor to those of a low-dimensional metal-like material.
