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
