摘要/Abstract
合成和表征了两种新型的基于四苯基乙烯的四齿唑盐: 1,1,2,2-四[(2'-(N-甲基咪唑-1-基)乙氧基苯基)]乙烯六氟磷酸盐(1)和1,1,2,2-四[(2'-(N-吡啶甲基苯并咪唑-1-基)乙氧基苯基)]乙烯六氟磷酸盐(2)通过荧光光谱, UV/vis光谱, HRMS, 1H NMR和红外光谱研究了1对阴离子和2对阳离子的识别性能. 结果表明: 通过荧光方法, 1能够将 $H_{2}PO_{4}^-$与其他阴离子区分开, 2能够将Ag+与其他阳离子区分开.

Two new tetraphenylethylene-based tetradentate azolium salts, 1,1,2,2-tetrakis{[2'-(N-methyl-imidazolium-1-yl)ethoxyl]phenyl}ethylene hexafluorophosphate (1) and 1,1,2,2-tetrakis{[2'-(N-picolyl-benzimidazolium-1-yl)ethoxyl]phenyl}ethylene hexafluorophosphate (2), were synthesized and characterized. Recognitions of 1 for anions and 2 for cations were studied through fluorescence spectra, UV/vis spectra, HRMS, 1H NMR and infrared spectroscopies. The results revealed that 1 was able to differentiate $H_{2}PO_{4}^-$ from other anions, and 2 was able to differentiate Ag+ from other cations via fluorescence method.
Key words: tetraphenylethylene, azolium salts, fluorescence, recognition, ions
