本文设计合成了4个双臂2,4-二硝基苯腙衍生物作为F-和H2PO4-阴离子的比色法检测用探针主体,并得到其中一个主体的单晶结构.4种受体可以通过溶液颜色的变化选择性识别F-和H2PO-4.UV-Vis和1H NMR光谱研究表明受体与F-和H2PO-4的作用都形成氢键,与F-作用还伴随一个脱氢过程.

Four of two branched bis-2,4-dinitrophenylhydrazones were prepared as colorimetric anion receptors, which recognize F- and H2PO4- selectively in solution of DMSO through hydrogen binding. Single crystal of one of the compounds was obtained (CCDC: 298951). The UV-Vis titration with F- or H2PO4- revealed that new intense absorption bands for all of receptors accompanied by dramatic color changes with the association constants in the range of 104～105·mol-1.The UV-Vis and 1H NMR investigation indicated that the hydrogen bonds were formed between F- or H2PO4- and receptors, and there was also a deprotonation of binding fragment during the hydrogen bond formation in the case of F-.
