Structural and optical studies of fluoride ion binding using N-heteroaromatic ligands

Abstract

8-hydroxyquinoline and imidazole, two important N-heteroaromatic systems, have a strong affinity towards various anions via their acidic OH or NH protons. Three receptor ligands, 5-(1H-benzo[d]imidazol-2-yl)quinolin-8-ol (1), 5-(benzo[d]thiazol-2-yl)quinolin-8-ol (2), and 4-(1H-benzo[d]imidazol-2-yl)benzene-1,3-diol...
