The synthesis, characterization and binding studies with anions for biaryl-based anion receptors bearing thiourea groups have been described. The results revealed that receptors (1 and 2) showed good selectivity and binding affinity for F-, and among them binaphthyl-based receptor (1a) showed the best binding affinity for F-in comparison to other tested anions (Cl-, Br-, I-, NO-3 ; HSO-4 ; AcO-And H2PO-4 ). This is probably due to the fact that the moderate rigidity of binaphthyl skeleton in 1a is able to provide the better geometry of two thiourea groups for incorporating F-into the binding pocket. The higher basicity of F-Also participated in this selectivity. Springer Science+Business Media Dordrecht 2013.
