The constitutes and isomer distribution of di-（potassium sulfonate）-di-phthalimidomethyl phthalocyanine zinc

Sulfonate and/or phthalimidomethyl phthalocyanine zincs are obtained by the condensation reaction of anhydrous zinc acetate and two precursors, i.e. 4-phthalimidomethyl phthalonitrile and 4-（potassium sulfonated） phthalonitrile. The ZnPCSnPm mixture was separated into 5 components according to the number of substituted sulfonate groups and each component which has the same chemical constituent consists of different regioisomers. An HPLC method in isocratic conditions was developed to exercise quality control and make quantitative analysis of the photosensitizer, di-（potassium sulfonate）-diphthalimidomethyl phthalocyanine zinc （abbreviated as ZnPcS2P2, here, S represents sulfonate group, P the phthalimidomethyl group and ZnPc the phthalocyanine zinc）. Furthermore, by comparing the retention behavior of ZnPcS2P2 with that of ZnPcS2, positional structure of isomers of ZnPcS2P2 was speculated. Reversed-phase HPLC method with TEA-phosphate buffer and DMF as eluents in gradient conditions has been proved to be a powerful tool for the separation of such complex system.     

异丙嗪旋光异构体的毛细管区带电泳分离

研究用不同的手性选择剂拆分异丙嗪旋光异构体。用手细管区带电泳法拆分异丙嗪旋光异构体。研究表明,用低浓度β－环糊精（β－ＣＤ）可基线分离异丙嗪旋光异构体,用谷氨酸－β－ＣＤ不能基线分离,而用由两者组成的混合手性剂体系所造成的分离介于用各单个手性选择剂所造成的分离选择性之间,在一些混合比例下也可其线分离异丙嗪旋光异构体。手性选择剂的种类和浓度对分离结果有较大影响。
