The syntheses, photophysical properties and in vitro biological behavior of a series of nine Zn((II))-phthalocyanines (ZnPcs) bearing one to eight positively-charged trimethylaminophenoxy groups are reported. All ZnPcs are highly soluble in polar organic solvents, and show fluorescence and singlet oxygen quantum yields in the ranges 0.11-0.21 and 0.16-0.47, respectively. The cytotoxicity of the ZnPcs depends on both the number of charges and their site of substitution (α vs. β) on the Pc isoindole units; the most promising for PDT application are the α-substituted di-cationic ZnPcs 6a and 17a.
报道了一系列九个带有一至八个带正电荷的三甲基氨基苯氧基的锌(II)酞菁(ZnPc)的合成、光物理性质及体外生物学行为。所有的ZnPc在极性有机溶剂中都具有高溶解性,并且分别显示出荧光量子产率在0.11 - 0.21范围内以及单线态氧量子产率在0.16 - 0.47范围内。ZnPc的细胞毒性取决于电荷数量及其在酞菁异吲哚单元上的取代位置(α位与β位);对于光动力疗法(PDT)应用最有前景的是α位取代的二价阳离子ZnPc 6a和17a。
