Resumen
[EN] The synthesis of two new 2,7-disubstituted phenanthrene-based bis oximes is described. The ability of these two compound for complexing heavy metal cations have been studied and complexation constants and complex stoichiometry for Cr3þ and Fe3þ complex have been determined. The fluorescent properties of ligand 2 make this compound able to act as a sensor able to discriminate between Cr3þ and Fe3þ. Detection limits for these two cations have been evaluated. 2012 Elsevier Ltd. All rights reserved.
