摘要：

Pyrene appended benzimidazolium-based simple cleft 1 has been synthesized. The open cleft of 1 distinguishes H2PO4- and F- selectively by showing binding induced different emission characteristics in CH3CN. The chemosensor 1 also functions in aqueous CH3CN and shows marked change in emission in the presence of sodium phosphate at pH 6.5 and AMP at pH 7.3. Binding studies have been carried out using fluorescence, UV-vis and H-1 NMR spectroscopic techniques. (C) 2011 Elsevier Ltd. All rights reserved.
