摘要：

Three new tricarbonyl rhenium(l) polypyridine complexes containing amide, urea and thiourea derivatives of 2,2'-bipyridine ligands L1-L3 have been synthesized, characterized and found to show significant UV-visible absorption spectral changes on the addition of anions CN-, F-, CH3COO- and H2PO4-. These spectral changes and H-1 NMR titrations of complexes 1-3 with anions indicate strong binding of anions with the Re(I) complexes and the binding constants are in the range of 10(3)-10(5) M-1. The strong binding is attributed to the H-bond formation/deprotonation of - NH proton in the ligand and the selectivity of anion is in the order CN- > F- > CH3COO- > H2PO4-. (C) 2013 Elsevier B.V.
