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 2 PO 4−...
The imidazole ring unit in both 2‐(2′‐hydroxyphenyl)‐benzimidazole (ligand a) and a europium(III) complex exhibited specific luminescent responses in the presence of fluoride anions. UV‐visible and 1H‐nuclear magnetic resonance spectra showed that the NH bond of the imidazole ring can form a hydrogen bond with added fluoride anions. The detection limits are 5 × 10−6 m for organic ligand and 1.0 ×...
