Synthesis and Characterization of New Asymmetrical Phthalocyanine Zinc

Four kinds of symmetrical phthalocyanine zincs (PCZn) 2(3),9(10),16(17),23(24)-(tetraheptanylcarbonyl amino)-phthalocyanine zinc, 2(3),9(10), 1 6(17),23(24)-tetramethoxy-phthalocyanine zinc, 2(3),9(10), 1 6(17),23(24)-tetra-(4-tert-butylphenoxyl)-phthalocyanine zinc, and 2(3),9(10),16(17),23(24)-tetraphenoxyl-phthalocyanine zinc were synthesized from 4-nitro-phthalonitrile. Moreover, the 4-(4-tert-butylphenoxyl)phthalonitrile was employed as a precursor in the synthesis of two kinds of asymmetrical PCZn (A(3)B) containing either amino- or carboxyl-group by probability method.
