The　monomer　electronic　absorption　spectra　of　the　ZnPcS2P2　(disulfonated　diphthalimidomethyl　phthalocyanine　zinc)　in　11　kinds　of　solvents　and　5　kinds　of　unsubstituted　metal　phthalocyanines　in　DMF　were　investigated.　The　monomer　electronic　absorption　spectra　of　some　substituted　phthalocyanine　zinc　including　ZnPcS4　(tetrasulfonated　phthalocyanine　zinc),　ZnPcS4　(tetraphthalimidomethyl　phthalocyanine　zinc),　ZnPc(NO2)4　(tetranitro　phthalocyanine　zinc)　and　ZnPcS2P2　in　the　same　solvent　were　also　studied.　The　result　showed　that　(1)　with　the　strengthening　of　coordination　ability　of　the　solvent,　the　maximum　absorption　wavelength　of　ZnPcS2P2　increased　slightly.　(2)　with　the　increasing　of　electronegativity　of　central　ion,　the　maximum　absorption　wavelength　of　MPcs　had　a　little　blue　shift.　(3)　the　electron-donating　substituting　group　caused　slightly　blue　shift.　The　monomer　fluorescence　spectra　of　ZnPcS4,　ZnPcP4,　and　ZnPcS2P2　in　different　solvents　were　determined.　The　result　showed　that　(1)　the　electron-withdrawing　substituting　group　caused　slightly　red　shift　of　the　fluorescence　spectra.　(2)　with　the　strenghtening　of　coordination　ability　of　the　solvent,　the　maximum　emission　wavelength　increased　slightly.　(3)　the　fluorescence　intensity　of　ZnPcS2P2　in　the　solution　which　contains　Cremophor　EL　was　remarkable　stronger　than　that　in　other　solvents.　This　is　an　important　suggest　to　the　development　of　photodynamic　diagnose　agent.　The　effect　of　solvents,　central　ions　and　substituents　on　spectra　were　partly　explained　by　means　of　the　quanturm　chemistry.
