METHOD OF APPLYING THIN FILMS TO SUBSTRATES

摘要

A method of preparing a thin film of a phthalocyanine compound on a substrate comprising forming a thin layer of the phthalocyanine compound on the surface of a suitable liquid and passing the substrate through the layer so that a film of the phthalocyanine is deposited upon the surface of the substrate. Very thin films are formed and the resulting composite articles are useful in the manufacture of electronic, electrical, electrochemical and photochemical devices of high sensitivity.
