Abstract | Two novel luminescent europium (III) tris(dibenzoylmethane) (Eu(dbm) 3) with 2-indole-3-yl-imidazo [4,5-f]-1,10-phenanthroline (a) and 2-(2-nitrophenyl)-imidazo [4,5-f]-1,10-phenanthroline (b) complexes were prepared as anion receptors. It was found that Eu(dbm) 3(a), which give rise to intense yellow emission, can selectively recognize F - and H 2PO 4- by changing its color from yellow to green. However, Eu(dbm) 3(b) with red emission could generate luminescent quenching by F - and H 2PO 4-. These sensing materials were characterized by UV-vis, fluorescence and NMR, indicating that the recognition processes were attributed to the synergistic effects of hydrogen-bonding and competitive coordination interactions between the ligands and anions. © 2012 Elsevier B.V.
