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

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 intermolecularπ-πorbital overlap between the Pc molecules. In this paper, we report on the conversion of bulkFeIII(Pc)(SCN)npolymeric organic conductor into crystalline nanostructures through horizontal vapor phase growth process. The needle-like nanostructures are deemed to provide more ordered and, thus, moreπ-πinteractive interskewerFeIII(Pc)(SCN)npolymer orientation, resulting in a twofold increase of its electrical conductivity per materials density unit.
