| Description |
A family of fluoroionophores have been synthesized incorporating Ru(II)-bipyridine moiety as fluorogenic unit and amino/benzenesulphonamido functionalized 1,10-phenanthroline moiety, attached to Ru(II), as binding sites. Two of the ligands and one of the complexes have been characterized crystallographically. Anion recognition property, studied by luminescence, UV-vis and (1)H NMR spectroscopy, with a large number of anions exhibit strong complexation with F(-), H(2)PO(4)(-) and AcO(-). Binding constants have been determined from luminescence titration and (1)H NMR study gave insight about binding site of anions. Bidentate chelating nature of the H(2)PO(4)(-) and AcO(-) anions and steric crowding created by benzenesulphonamide moiety has significantly influenced binding constants and selectivity.
