摘　　要：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.
