A series of pegylated cis-A2B2- or A3B-type ZnPcs , substituted on the α-positions with tri(ethylene glycol) and hydroxyl groups, were synthesized from a new bis-phthalonitrile. A clamshell-type bis-phthalocyanine was also obtained as a byproduct. The hydroxyl group of one ZnPc was alkylated with 3-dimethylaminopropyl chloride to afford a pegylated ZnPc functionalized with an amine group. All mononuclear ZnPcs were soluble in polar organic solvents, showed intense Q absorptions in DMF, and had fluorescence quantum yields in the range 0.10–0.23. The clamshell-type bis-phthalocyanine adopts mainly open shell conformations in DMF, and closed clamshell conformations in chloroform. All ZnPcs were highly phototoxic to human carcinoma HEp2 cells, particularly the amino- ZnPc mainly protonated under physiological conditions, which showed the highest phototoxicity (IC50 = 0.5 μM at 1.5 J/cm2) dark cytotoxicity (IC50 = 22 μM), in part due to its high cellular uptake. The ZnPcs localized in multiple organelles, including mitochondria, lysosomes, Golgi and ER. 
以一种新的双
酞腈为原料,合成了一系列在 α 位上被三(
乙二醇)和羟基取代的 Pegylated cis-A2B2- 或 A3B 型 ZnPcs。作为副产品,还得到了一种蛤壳型双
酞菁。一个 ZnPc 的羟基被 3-
二甲氨基丙基
氯烷基化,从而得到一个用胺基团官能化的聚合 ZnPc。所有单核 ZnPcs 都可溶于极性有机溶剂,在 
DMF 中显示出强烈的 Q 吸收,荧光量子产率在 0.10-0.23 之间。蛤壳型双
酞菁在 
DMF 中主要呈开壳构象,在
氯仿中呈闭壳构象。所有 ZnPcs 对人癌 HEp2 细胞都有很强的光毒性,尤其是在生理条件下主要质子化的
氨基 ZnPc,其光毒性(IC50 = 0.5 μM,1.5 J/cm2)和暗细胞毒性(IC50 = 22 μM)最高,部分原因是其细胞吸收率高。ZnPcs 定位于多个细胞器,包括线粒体、溶酶体、高尔基体和 ER。
