The synthesis and the binding properties of novel phthalonitrile derivatives 1-3 towards metal cations have been described in this paper. The complexation and extraction of some transition and heavy metal cations have been followed by UV-visible spectrophotometry absorption in methanol. The conductivity studies have been used in order to confirm complex’s stoichiometries. The treatment of UV spectra by digital program showed the formation of ML (with ML2 in some cases) (M=metal, L=ligand) species. Beyond the discussion of the stability profiles of complexes particular attention is paid to the selectivity towards Cu2+ in the 1st sequence of transition metal cations and towards Hg2+ in the sequence of heavy metal cations.
