This paper describes the preparation and Langmuir-Blodgett (LB) monomolecular film formation of H2

Co

and Zn phthaloeyanine compounds with p-vinyiphenoxy peripheral substituent on each benzo ring at either 2- or 3- position [i.e.

tetra (p-vinylphenoxy) substituted isomer mixture]. These phthalocyanine derivatives form stable LB films at the film pressures greater than 10 dynes/cm. The surface pressure-area isotherms indicate that the phthalocyanine units are densely packed with a eofacial orientation.Schottky cells of [Indium-Tin Oxide/LB film/Al] were prepared and their electronic properties were examined.Much better rectifying properties
