光敏剂产生单线态氧的能力是评价其光动力活性的因素之一。采用2,5-二甲基呋喃为吸收剂,通过高效液相色谱法研究了1-3代硝基芳基苄醚树枝配体轴向取代酞菁硅(Ⅳ)单线态氧的生成速率、生成速率常数及量子产率。结果表明,轴向取代酞菁硅(Ⅳ)单线态氧的生成速率和生成速率常数均随着树枝代数的增加而逐渐增大,低代的树枝配体轴向取代酞菁硅(Ⅳ)的单线态氧量子产率较高,这可能与不同代树枝配体对酞菁核的位点分离有关。研究将为开发轴向取代酞菁硅(Ⅳ)配合物作为新型光敏剂提供重要的理论参考。
光敏劑產生單線態氧的能力是評價其光動力活性的因素之一。採用2,5-二甲基呋喃為吸收劑,通過高效液相色譜法研究瞭1-3代硝基芳基芐醚樹枝配體軸嚮取代酞菁硅(Ⅳ)單線態氧的生成速率、生成速率常數及量子產率。結果錶明,軸嚮取代酞菁硅(Ⅳ)單線態氧的生成速率和生成速率常數均隨著樹枝代數的增加而逐漸增大,低代的樹枝配體軸嚮取代酞菁硅(Ⅳ)的單線態氧量子產率較高,這可能與不同代樹枝配體對酞菁覈的位點分離有關。研究將為開髮軸嚮取代酞菁硅(Ⅳ)配閤物作為新型光敏劑提供重要的理論參攷。

The singlet oxygen(102) production capabilitity of photosensitizers is an important factor to assess their potential as effective photodynamic therapy(PDT) agents. In this paper, the 102 production rate, produc- tion rate constant and quantum yield of silicon(IV) phthalocyanine axially bearing 1-3rd generations poly(nitro aryl benzyl ether) dendritic substituents were evaluated by a high performance liquid chromatographic method. The results show that the 1O2 production rate and production rate constant of these compounds increase gradu- ally with dendritic generations increase. And the 102 quantum yield of silicon(IV) phthalocyanine with 1St gen- eration dendritic ligand was the highest. This may be due to the isolation effect of the dendritic ligands on the phthalocyanine core. The parameters of the observed 102 production properties will provide valuable data for these dendrimer phthalocyanines as promising photosensitizer in PDT application.
