The anion sensing ability of compound 1 based on a novel 2,4-dinitrophenylhydrazone derivative was studied through "naked-eye" experiment, UV-Vis spectral titration, and (1)H NMR titration. Sensor 1 was synthesized through a simple method with high yield. The solution of host 1 turned deep purple from light purple in the presence of the strong basic anions and turned yellow upon addition of the weak basic anions, respectively. The results could be explained on the basis of transfer of the tautomeric equilibrium of sensor 1 induced by anions with different basicity.
通过“肉眼”实验、紫外-可见光谱滴定和核磁共振氢谱滴定，研究了基于新型2,4-二硝基苯腙衍生物的化合物1的阴离子传感能力。传感器1通过一种简单的方法合成，产率很高。在强碱性阴离子存在下，主体1的溶液从浅紫色变为深紫色，加入弱碱性阴离子后变为黄色。这些结果可以基于不同碱性阴离子诱导传感器1互变异构平衡的转移来解释。
