摘　　要：A water soluble poly-[tetrakis-(2,3-dicarboxylate phenoxy) methyl methan] aluminum phthalocyanine (AlPPc.(COOH)x) has been synthesized from the cyclization of tetranuclear phthalonitrile and successive hydrolysis of cyano in alkaline solution. The absorption spectra showed low aggregation of this compound in pH 9.18 buffer than that of existing water soluble phthalocyanine compounds. With the addition of Triton X 100, an enhancement of fluorescence emission with quantum yield from 0.4 to 0.83 was observed; contrarily, it was thoroughly quenched by the addition of CATB in suit. A longer life time of singlet state was also detected in presence of Triton X 100. The result indicates that AlPPc.(COOH)x is desired to investigate in fluorescent probe or in fluorescence imaging diagnose.A water soluble poly-[tetrakis-（2,3-dicarboxylate phenoxy） methyl methan] aluminum phthalocyanine （AIPPc.（COOH）x） has been synthesized from the cyclization of tetranuclear phthalonitrile and succes- sive hydrolysis of cyano in alkaline solution, The absorption spectra showed low aggregation of this compound in pH 9.18 buffer than that of existing water soluble phthalocyanine compounds.
