Abstract | A novel 2-(2-pyridyl)benzimidazole (a) compound with hydrogen bond unit was synthesized as an anion receptor. It is noteworthy that only fluoride anions can led to its fluorescence change from ultraviolet (362 nm) to visible region (408 nm) compared with AcO-, Cl-, Br-, and I-. Spectroscopic studies demonstrated that the recognition process can be attributed to the hydrogen bonding interactions between F- and the imidazole-NH. More importantly, this ligand can coordinate to europium ion and a novel europium complex Eu(a)3(NO3) 3·H2O possessing red emission was prepared. We noted that the luminescence of this complex can be completely quenched by F - as well as AcO-. However, we recognized that the competitive coordination interactions between anions and ligand resulted in the quenching effects. © 2013 Elsevier B.V. All rights reserved. |
