Anion recognition properties of 2,2'-bipyridine derivative receptors containing phenol group.
A series of artificial 2,2'-bipyridine receptors (1, 2, 3) containing phenol group have been designed and synthesized. Their anion-binding properties are evaluated for various anions (F(-), Cl(-), Br(-), I(-), AcO(-) and H(2)PO(4)(-)) by UV-vis titration experiment in order to research the impact of different substituents on anion-recognition properties. Results indicate that the anion binding abilities can be tuned by electron push-pull properties of substituents on the phenyl ortho- or para-position of the receptors. In addition, receptor 1 is sensitive for F(-) detection without the interference of other studied anions, and receptors 2 and 3 are sensitive for H(2)PO(4)(-) detection.
