Synthesis and characterization of potassium salt of metal-free β-tetrasulfophthalocyanine

目的采用新方法合成水溶性四-β-磺酸钾基无金属酞菁。方法本文以4-磺酸钾基邻苯二甲腈为原料,通过醇锂置换法合成得到四-β-磺酸钾基无金属酞菁,目标产物经过红外吸收光谱、紫外-可见电子吸收光谱、核磁共振氢谱和质谱的表征。结果目标产物产率75%,其在30%CH3OH/H2O溶剂中Q带呈无金属酞菁两个典型的特征分裂峰,分别位于658nm和693nm。结论利用醇锂液相法合成目标产物产率高,副产物少,后处理简单。

OBJCECTIVE Potassium salt of metal-free β-tetrasulfophthalocyanine was prepared and characterized.METHODS The title complex was synthesized from potassium 4-sulfophthalonitrile by condensation method.The product was characterized with IR,UV-vis,1HNMR and MS.UV-visible electronic absorption spectra of the title complex in different solvents was determined.RESULTS The yield of the title complex is 75% and its maximum absorption wavelength of Q band is 658nm and 693nm in 30% CH3OH/H2O.CONCLUSION The method is suitable for the preparation of potassium salt of metal-free β-tetrasulfophthalocyanine due to the high yield and no by-product.
