【Abstract】 Four new substituted phthalonitriles such as 3-(5-aminonaphthoxy) phthalonitrile(C18H11N3O),4-(5-aminonaphthoxy) phthalonitrile(C18H11N3O),3-biphenyloxy-phthalonitrile(C20H12N2O) and 4-biphenyloxy-phthalonitrile(C20H12N2O) have been synthesized,which are converted into the corresponding phthalocyanine-zinc(Ⅱ) complexes with aryloxy substitunents :tetra-alpha-(5-aminonaphthoxy) phthalocyanines zinc(Ⅱ)(C72H44N12O4Zn),tetra-β-(5-aminonaphthoxy) phthalocyanines zinc(Ⅱ)(C72H44 N12O4Zn),tetra-alpha-biphenyloxy-phthalocyanines zinc(Ⅱ)(C80H48N8O4Zn) and tetra-β-biphenyloxy-phthalocyanines zinc(Ⅱ)(C80H48N8O4Zn).Their maximum absorption wavelength,molar extinction coefficient,emission wavelength,fluorescence quantum yields(ФF),the singlet oxygen quantum yields(ΦΔ),and photodegradation constant(k) have been measured by the UV-Vis absorption and fluorescence spectra.The structure-activity relationship have been discussed in comparision with their analogues.The results show that tetra-alpha-biphenyloxy-phthalocyanines zinc(Ⅱ) has large extinction coefficient in the red visible region of the light with relatively higher singlet oxygen quantum yield,it is a promising photosensitizer for use in photodynamic therapy.更多还原
