摘要

A series of new model complexes of 2,4-dihydroxybenzaldoxime (H3L) with divalent copper and nickel ions having a general formula [M(H2L)(2)]center dot sol (sol = solvent or nitrogen containing heterocycle) and a new zinc complex [Zn(H2L)(2)(pep)(2)] (where pep = 4-(2-(pyridine-4-yl)propyl)pyridine) were synthesized for the detection of fluoride ions. All complexes were structurally characterized by X-ray single crystal diffraction, powder X-ray diffraction and conventional spectroscopic tools. All these complexes show selective interactions with tetrabutylammonium fluoride. The position of the new UV-Vis absorption in each of these complexes in the presence of fluoride ions is guided by the electronic configuration of the metal ion. The complex [Zn(H2L)(2)(pep)(2)] has a distinct advantage over the other model complexes, as it can detect fluoride ions through both emission and absorption spectroscopy.
