| 摘 要： | 两亲性金属酞菁配合物二磺酸基二邻苯二甲酰亚胺甲基酞菁锌（ＺｎＰｃＳ２Ｐ２）能有效选择地滞留在组织中，是一种新型的光动力治疗肿瘤的光敏剂。有关酞菁化合物治疗肿瘤的机制目前还不清楚，而对ＣＥＬ溶液中该光敏剂状态的研究对阐明其机制有重要意义，本文对不同浓度ＣＥＬ溶液中的二磺酸基二邻苯二甲酰胺甲基酞菁锌的吸收光谱和荧光光谱进行了研究，探讨了它在溶液中的聚集状态，通过分析确定其聚集态为二聚体，并获得其平衡常数和单体的摩尔吸光系数。

| Abstract: | Sulfonated Phthalimidomethyl Zinc Phthalocyanine is a new photodynamic therapy reagent,it can be selectively attacked to cell,but how it attacks the target cell is still unknowable.The aggregation state of photosensitizer is significant to its mechanism proved in CEL solution.The aggregation of ZnPcS 2P 2 in CEL has been studied with absorption spectroscopy and fluorescence spectroscopy.The aggregation state is dimer through theory analysis,monomer molar absorption coefficient as well as equilibrium constant were estimated. |
