设计并合成了邻菲罗啉并咪唑类阴离子受体2-(4-溴苯酚基)-1H-咪唑[4,5-f ][1,10]邻菲罗啉,对其进行了紫外-可见,X衍射单晶衍射表征。通过荧光滴定、理论计算和晶体结构分析,研究了受体对5种阴离子(F-、Cl-、Br-、I-、H2PO2-4、CH3COO-)的传感作用及作用机理。结果表明受体对CH3COO-、F-、H2PO2-4有很强的传感作用,形成1:1的氢键超分子,对Cl-的作用较弱,对Br-、I-没有明显传感作用。

Anion receptors of 2-(4-Br-phenoly)-1H-imidazo[4,5-f ][1,10]phenanthroline (TM) was designed and synthesized, and the structure was confirmed through single crystal X-ray diffraction. Anion sensing and the mechanism studies were carried out by UV-vis spectroscopy, fluorescence titration. The receptors exhibited sensing towards CH3COO- , F-, H2PO2-4 , and weakly sensing towards Cl- with inconspicuous response towards Br-, I-. The receptors formed hydrogen bond supramolecular with anions F-, H2PO2-4 , CH3COO- as 1:1. The receptors formed hydrogen bond supramolecular with Cl-.
