Abstract : This invention relates general to phthalocyanine compounds, and more particularly to the preparation of aryloxy, arylthio, alkyloxy, and alkylthio phthalocyanine compounds and their subsequent incorporation into semiconducting thin films by the Langmuir-Blodgett technique. One object of the current invention is to modify phthalocyanine so that it can be used in film deposition techniques that operate with compounds soluble in organic solvents, one of which is the Langmuir-Blodgett film transfer technique. Another object of the invention is to produce orderly films from the chemically modified phthalocyanine that have electrical and other properties similar to, and better than, those of conventional phythalocyanines. Another object is to produce phthalocyanines suitable for Langmuir-Blodgett film transfer without the need for difficult carbon atom substitution on the phthalocyanilne ring. These and other objects are achieved by attaching aryloxy or arylthio or alkyloxy or alkylthio substitution at up to four points about the periphery of a phthalocyanine ring. The resulting compounds dissolve in organic solvents and are suitable for the making of Langmuir-Blodgett films.
