They have very good solubility in many common organic solvents. Their electronic absorption spectra and fluorescence emission spectra were measured. These SubPcs have a maximum absorption at 570 nm, which are blue shifted about 100 nm compared with corresponding phthalocyanine. When β position substituent is —OCH 2C(CH 3) 3 , the SubPc(2b) has fluorescence emission peaks at 415 and 608 nm. However, when there are two substituents at α position, the SubPc(2c) has only one fluorescence emission peak at 435 nm.展开更多

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)-di-phthalimidomethyl 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.展开更多
