The syntheses,characterization and properties of some metallophthalocyanine complexes substituted by(N-(2-hydroxyethyl)piperazine)-N'-2-ethane sulfonic acid(HEPES)

摘要

Eight novel piperazine derivatives of metal(Zn,Co,Ni,Cu)phthalocyanine complexes were synthesized from two precursors obtained by the nucleophilic substitution of(N-(2-hydroxyethyl)piperazine)-N'-2-ethane sulfonic acid(HEPES)with both 3-nitro-phthalonitrile and 4-nitro-phthalonitrile.The complexes are characterized by IR,elemental analysis,~1H NMR and mass spectroscopy;the UV-vis absorption spectra,rate of singlet oxygen yields,fluorescence spectra and quantum yields of the compounds are discussed.
