PREPARATION AND PROPERTIES OF TETRA (p-VINYLPHENOXY) METALLOPHTHALOCYANINES

Received Date: 10 July 1987

This paper describes the preparation and Langmuir-Blodgett (LB) monomolecular film formation of H2, Cu, Ni, 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,diode parameter,break-down potential and mechanical strength were notified by the post-polymerization of LB-layers.On exposing the polymerized films to tetrahydrofuran vapor,the absorption maxima of Q-band shift bathochromically by about 100nm,being sensitive to diode laser light.
