Molecular precursors phthalimidomethyl phthalic acid and phthalimidomethyl phthalonitrile were synthesized for the first time and both were able to condensation to form tetra phthalimidomethyl phthalocyanine zinc through “ammomium molybdate method” and “DBU method ”respectively. The precursors and title compounds were characterized by element analysis, IR, UV/Vis as well as NMR. The two synthesis methods were compared, the result indicated that using the phthalimidomethyl phthalic acid as precursor through the former method, the product was an isomer with C4h symmetry, while using phthalimidomethyl phthalonitrile as precursor through the latter method, the products were a mixture of different isomers.
