摘要：

Poly (nitro aryl benzyl ether) dendritic ligands axially substituted phthalocyanine silicon (IV) is an effective approach to reduce the formation of aggregation leading to higher photodynamic therapy efficacy. The photophysical properties of 1-3rd generations poly(nitro aryl benzyl ether) dendritic ligands axially substituted phthalocyanine silicon (IV) were studied by UV-Vis, steady-state fluorescence and time-resolved fluorescence spectrum. With the dendrimer increased, the intensity of fluorescence, singlet state lifetimes and Q band absorption spectra of phthalocyanine core increased, while their fluorescence quantum yield decreased gradually. G(3)-SiPc(NO2)(16) can be regarded as an ideal photosensitizer and may have a high potential utility for in vivo photodynamic therapy applications.
