利用荧光光谱法考察了化合物二对甲基苯磺酸1,4-苯二酚酯对阳离子Fe3+、Mn2+、Nd2+、Ni2+、Hg2+、Zn2+、Cu2+、Co3+和阴离子F-、Cl-、Br-、I-、ClO4-、H2PO4-、AcO-、PhCOO-的识别性能。结果表明,该化合物对阴离子没有识别效果,对Fe3+具有很好的识别能力,其络合常数K值达到1.98×108L/mol。二对甲基苯磺酸1,4-苯二酚酯与Fe3+基本形成1∶2型的络合物。本文从主客体的大小形状匹配及配位识别原子等方面对受体的识别能力进行了讨论,发现了一个独特有趣的夹心三明治结构。
The effects of 1,4-benzenediol di-p-toluenesulfonate on cation Fe3 +, Mn2 +, Nd2 +, Ni2 +, Hg2 +, Zn2 +, Cu2 +, Co3 + and anion F-, Cl-, Br- were investigated by fluorescence spectroscopy. I-, ClO4-, H2PO4-, AcO-, PhCOO- recognition performance. The results show that the compound has no recognition effect on the anion and has good recognition ability for Fe3 +, and the complexation constant K value reaches 1.98 × 108 L / mol. 1,4-Benzenediol bis-p-toluenesulfonate and Fe3 + basically form a 1: 2 type complex. In this paper, the ability of receptor recognition is discussed from the aspects of size and shape matching between host and guest, as well as the coordination recognition atom. A unique and interesting sandwich sandwich structure was found.
