一种新型四羧基(1,4-二噻英)四氮杂卟啉镁季铵盐的合成与表征

Synthesis,Characterization and Spectroscopic Properties of A Novel Quaternary Ammonium of Magnesium Tetra-Carboxyl(1,4-dithiin) Porphyrazine

成功合成了四羧基(1,4-二噻英)四氮杂卟啉镁[MgPz(dtn-COOH)4]及其十六烷基三甲基铵盐[MgPz(dtn-COO-.CTA+)4],并通过紫外可见光谱、红外光谱和荧光光谱对其进行了表征。结果表明,季铵盐的形成很好地改善了四羧基(1,4-二噻英)四氮杂卟啉镁的溶解性能;季铵盐不仅易溶于常见的有机溶剂,还可以很好地溶于不同pH值的水溶液。

Magnesium tetra-carboxyl（1,4-dithiin） propyrazine[MgPz（dtn-COOH）4]was synthesized by the hydrolytic action of MgPz（dtn-COOCH3）4 in NaOH aqueous solution.Its quaternary ammonium salt [MgPz（dtn-COO-·CTA＋）4] was prepared by the acid-base with hexadecyl trimethyl ammonium hydroxide（CTAOH）.The salt was soluble not only in common organic solvents,but also in aqueous solution with different pH values.These compounds were characterized by UV-Vis spectrum,fluorescence spectrum and IR spectrum.
