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　C-4h　symmetry,　while　using　phthalimidomethyl　phthalonitrile　as　precursor　through　the　latter　method,　the　products　were　a　mixture　of　different　isomers.
