邻苯二甲硫基二乙酸配合物的合成与表征

Synthesis and characterization of complexes of o-phenylenedimethylenethio diacetic acid with transition metals ions

报道了邻苯二甲硫基二乙酸和过渡金属铜(II)、镉(II)、镍(II)配合物的合成,并通过元素分析、ICP发射光谱、红外光谱、核磁共振谱、差热热重分析等对它们进行了表征,结果表明:配体与金属的比例为1:1,硫参与了配位。对配合物进行了荧光性能的研究,紫外荧光光谱显示它们无荧光性。一系列的研究说明:刚性杂环直接连硫乙酸是搭建新型材料可行的方法。

The new complexes of o - phenylenedimethylenethio diacetic acid, H2L with transition metal ions Cu （Ⅱ）, Cd（ Ⅱ）, Ni（Ⅱ） have been synthesized and characterized by elemental analysis, FT- IR spectra, ICP- Aes spectra,^1 H - NMR spectra, TG - DTA analysis. The results suggest that ligand compares to metal is one to one, and sulfur attaches itself to the partnership. Ultraviolet fluorescence spectrum study indicated that the complex had no fluorescence. A series of researches indicated： direct linkage of heterocyelic to thio - acetic acid is a feasible method for constructing a new material.
