A novel calix[4]arene fluorescent receptor for selective recognition of acetate anion

A novel bridged fluorescent calix[4]arene with 1,8-diaminoanthracene and glycine at the upper rim has been prepared, which exhibited selective recognition towards AcO− over other anions such as F−, Cl−, Br−, H 2 PO 4 - , NO 3 - , I− and HSO 4 - by fluorescence spectroscopy and 1H NMR method.
