  Pyrenyl-appended imidazolium receptor for selective fluorescence sensing of oxalic acid

  摘要：

  A new fluorescent imidazolium-based cholestane receptor 4 bearing a pyrene moiety was synthesized. The binding ability of 4 toward various dicarboxylic acids was examined by UV-vis and fluorescence spectroscopy. Receptor 4 showed the highest binding constant for oxalic acid among all the tested dicarboxylic acids (K-a = 5.06 x 10(4) M-1). Oxalic acid formed a complex with 4 with a 1:2 ratio in ethanol.

  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.
