New Type Of Impurity Atom Pairs To Replace The Synthesis And Spectral Properties Of Zinc Phthalocyanine Complexes

Three novel disubstituted phthalocyanine zinc compounds:β-di(meta/para-N,N-dimethylaminophenoxyl phthalocyanine zinc(Ⅱ) [(CH3)2N(C6H5O)]2PcZn(Ⅱ)] (4a,4b) andβ-di(N,N-diethylaminoethylthio) phthalocyanine zinc(Ⅱ)[(C2H5)2N(C2H5S)]2PcZn (Ⅱ)(4c) have been synthesized by statistical condensation method. At the same time, three symmetrical phthalocyanine zinc compounds:β-octa(meta/para-N,N-dimethyl--aminophenoxyl phthalocyanine zinc(Ⅱ)][(CH3)2N(C6H5O)]8PcZn(Ⅱ)(5a,5b) andβ-octa(N,N-diethylaminoethylthio) phthalocyanine zinc(Ⅱ)][(C2H5)2N(C2H5S)]8PcZn(Ⅱ) (5c) have been synthesized. They were characterized by UV-vis absorption spectra, high performance liquid chromatography (HPLC), IR spectra, proton NMR spectra (1H NMR)and MALDI-TOF-MS.Electronic absorption spectra of these complexes have been measured in dichloromethane(CH2Cl2), tetrahydrofuran (THF) and N,N-dimethylformamide (DMF). The effect and situation of the substitute groups, solvents and concentrations were studied.The aggregation behavior of [(CH3)2N(C6H5O)]2PcZn(Ⅱ)] (4a,4b) was discussed in DMF, THF and CH2Cl2, and the aggregation behavior of [(C2H5)2N(C2H5S)]2PcZn(Ⅱ) (4c) was discussed in DMF and THF.The fluorescence spectra of disubstituted phthalocyanine zinc complexes have been measured in organic solvents. The effects of the substituted groups and solvents were studied on the maximum wavelength of emission and fluorescence intensity.
