Abstract:

Anions are ubiquitous in the world and play important roles in modern chemistry and life process, numerous efforts have been devoted to the design of acyclic receptors capable of selectively binding and sensing anions. Herein, several novel trinuclear ferrocene-based imidazole receptors 2a-2c were synthesized from the reactions of 1-(ferrocenylmethylene) imidazole with corresponding bromides 1a-1c. All of these receptors were characterized by H-1 NMR, C-13 NMR, MS, IR and elemental analysis. The anion binding studies were carried out by various techniques such as electrochemistry (CV and DPV) and H-1 NMR spectroscopy. Electrochemical behavior indicated that all the receptors displayed unique electrochemical sensing property for F- with a remarkable phenomenon; the previous peak of the free receptor gradually diminished, a new wave at more negative potential(Delta E-p >-150 mV) appeared due to the hydrogenation reaction. H-1 NMR titrations demonstrated that all the receptors could bind anions through (C-H)(+)center dot center dot center dot anion hydrogen bonds forming 1 : 1 stoichiometric complexes and had good fluoride binding ability in DMSO-d(6). Addition of F- caused deprotonation effect on the receptors, indicating the receptors showed better affinity for F-. Particularly, receptor 2b turned out to be a very good anion receptor with remarkably high preference in binding with F-.
