摘要
合成得到3-(5-氨基-萘氧基)邻苯二甲腈(C18H11N3O)、4-(5-氨基-萘氧基)邻苯二甲腈(C18H11N3O)、3-联苯氧基邻苯二甲腈(C20H12N2O)及4-联苯氧基邻苯二甲腈(C20H12N2O)4种未见报导的取代邻苯二甲腈,以此为前躯体合成了四[α-(5-氨基-萘氧基)]酞菁锌(C72H44N12O4Zn)、四[β-(5-氨基-萘氧基)]酞菁锌(C72H44N12O4Zn)、四[α-(联苯氧基)]酞菁锌(C80H48N8O4Zn)和四[β-(联苯氧基)]酞菁锌(C80H48N8O4Zn)4种未见报导的芳氧基取代酞菁锌配合物。通过测定它们的紫外-可见吸收光谱、荧光发射光谱,获得其最大吸收波长及其摩尔消光系数、最大发射波长、荧光量子产率(ΦF)、单线态氧量子产率(ΦΔ)及光降解速率常数并与其类似物进行了比较,探讨了它们的光物理光化学性质的构效关系。研究结果表明四[α-(联苯氧基)]酞菁锌在红光区具有大的摩尔消光系数,且具有较高的ΦΔ,有望开发成为光动力治疗用光敏剂。
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)(C72H44N12O4Zn), 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.
