Nanocrystalline Axially Bridged Iron Phthalocyanine Polymeric Conductor: (μ-Thiocyanato)(phthalocyaninato)iron(III)

Abstract

Skewered Iron(III) phthalocyanine conducting polymer can be constructed with the utilization of axial thiocyanato ligands ((μ-thiocyanato)(phthalocyaninato)iron(III)); (FeIII(Pc)(SCN)n) thereby creating additional avenues for electron transport through a linear SCN bridge, apart from the intermolecular π-π orbital overlap between the Pc molecules. In this paper, we report on the conversion of bulk FeIII(Pc)(SCN)n polymeric organic conductor into crystalline nanostructures through horizontal vapor phase growth process. The needle-like nanostructures are deemed to provide more ordered and, thus, more π-π interactive interskewer FeIII(Pc)(SCN)n polymer orientation, resulting in a twofold increase of its electrical conductivity per materials density unit.
