Two　kinds　of　substituted　phthalocyaninatozinc,　tetra-β-phthalimidobutoxy　phthalocyaninatozinc　(1)　and　tetra-β-phtha-limidomethyl　phthalocyaninatozinc　(2),　were　synthesized　by　mix　melting　method,　which　bear　the　same　phthalimide　substituents　but　the　linking　of　the　substituents　to　the　phthalocyanine　ring　is　different.　The　substituent　linking　to　the　phthalocyanine　ring　is　one　methylene　in　ZnPc　(2),　while　the　substituents　linking　to　the　phthalocyanine　ring　is　four　methylenes　and　one　anther　in　ZnPc(1),　in　which　anther　is　near　by　phthalocyanine　ring.　The　absorption　and　fluorescence　spectra　and　the　abilities　of　singlet　oxygen　generation　of　these　two　phthalocyanines　were　compared　with　respect　to　the　effect　of　different　linked　fashions.　The　magnitude　of　the　redshift　of　absorption　and　fluorescence　spectra　relative　to　unsubstituted　ZnPc　is　greater　for　tetra-β-phthalimidobutoxy　phthalocyaninatozinc　(1)　than　for　tetra-β-phthalimidomethyl　phthalocyaninatozinc　(2).　This　result　is　related　to　the　presence　of　stronger　electron　donating　peripheral　substituents　of　ZnPc　(1),　with　ΦF　of　(1)　is　larger　than　that　of　(2)　and　the　abilities　of　singlet　oxygen　generation　of　(1)　is　smaller　than　that　of　(2).
