Production of thin film of phthalocyanine compound

Abstract

Abstract PURPOSE:To obtain an electrodeposited thin film of a phthalocyanine compound useful as a catalyst and an organic electronic material, by dissolving an octaalkoxyphthalocyanine compound in an organic solvent, dipping a conductor into the solution and electrifying the solution using the conductor as a working electrode. CONSTITUTION:A compound of formula (R is 1-18C alkyl; M is H2, Mg, Cr, Mn, Fe, Cu, Zn, Pb, etc.) is dissolved in an organic solvent (e.g. dichloromethane, DMF, etc.), a supporting electrolyte (e.g. LiClO4) is added to the solution and the mixture is filled in an electrolytic cell. A conductor (e.g. Pt, graphite, etc.) and a counter electrode are inserted into the mixture to effect the electrolytic deposition of a thin film of a phthalocyanine compound on the conductor. The process enables the production of a thin film free from binder and having freely controllable thickness. The thin film has uniform composition and sufficiently high adhesivity to the substrate. The compound becomes insoluble in solvents other than concentrated sulfuric acid by the electrolytic deposition.
