A new imidazolium functionalized cholestane-based receptor 3 has been synthesized and characterized. A binding study of receptor 3 with various anions was assessed by UV-vis and fluorescence spectroscopy in dry CH3CN and aqueous CH3CN solutions. Of all anions, 3 showed the highest binding constant with dihydrogen phosphate (K-a = 1.6 x 10(5) M-1) accompanying a colour change in a dry CH3CN solution. (C) 2011 Elsevier Ltd.
