metal ions in phthalocyanine cavity are also investigated. Photodegradation, singlet oxygen and fluorescence quantum yields, and fluorescence lifetimes in dimethylformamide for the phthalocyanines are described. These properties of the compounds are very useful for photodynamic therapy applications and their high singlet oxygen quantum yields are very important for Type II mechanisms. The phthalocyanines
已实现了高度可溶于有机溶剂的新型无环或无环四甲氧基取代的金属,锌和铟酞菁的合成。酞菁的特点是UV -可见光谱,红外光谱,MALDI-TOF质谱,1 H NMR,1313 C NMR光谱学和元素分析。在其光谱,光化学和光物理性质上,还研究了取代基位置和酞菁腔中中心金属离子的变化。描述了酞菁在二甲基甲酰胺中的光降解,单重态氧和荧光量子产率以及荧光寿命。化合物的这些性质对于光动力疗法应用非常有用,其高单线态氧量子产率对于II型机理非常重要。酞菁可以作为II型光敏剂的合适候选者。
