Phthalocyanine compound
Abstract
Abstract NEW MATERIAL:The compound of formula Pc-(CONH-L-OH)n (Pc is phthalocyanine residue; L is lower alkylene; n>=1). EXAMPLE:The compound of formula Pc(CONH-CH2OH)4 [center atom: Co(II)]. USE:A phthalocyanine compound which can be polymerized by poly-addition condensation reaction. The addition polymer of the compound is useful as a deodorizing resin finishing agent, photorecording layer, carrier-formation layer for electrophotography, dye layer of solar cell, etc. PREPARATION:The objective phthalocyanine compound having 2, 4 or 8 amide groups on benzene ring can be synthesized by (1) synthesizing an amide derivative from trimellitic anhydride or its derivative, urea and a metal chloride, (2) adding an aqueous solution of an aldehyde (e.g. HCHO) selected according to the group L of the desired phthalocyanine compound of the above formula to the amide derivative and (3) reacting the components with each other in the presence of a basic catalyst such as sodium hydroxide at about room temperature for several hours-several tens hours.
