“…The amperometric study also shows that the sensitivity of the GCEr-ThM is higher than that of a bare electrode. All these results are in agreement with the ionophore character of the thyomacrocycle compound with respect to Cu(II) ions, previously observed [12,13].…”

A Langmuir-Schaefer (LS) film of a thiomacrocyclic (ThM) compound was deposited on the surface of a glassy carbon electrode (GCE) rod, from a subphase containing Cu(II) ions. The voltammetric response of this modified GCE when the ThM was bonded to Cu 2+ , showed that the LS film moved the oxidation peaks of copper to more positive values. On the other hand, a LS film of the ThM compound was deposited on the surface of a GCE rod from a subphase of pure water. When the voltammetric response of the GCE-ThM electrode was studied in a Cu 2+ -SO 4 2-solution, it was found that the modified electrode increases its sensitivity respect to Cu 2+ at low bulk Cu 2+ concentrations in solution, and a surface-complexation reaction is proposed to explain the effect of the LS film on the GCE surface.Keywords: modified electrodes, Langmuir-Schaefer films, cyclic voltammetry, surfacecomplexation reaction.

“…These copper ion carriers include a thiaglutaric diamide derivative [10], small size thia crown ethers [11,12], pyridine- [13] and phenanthroline-based aza-thio crowns [14], calix [4]arens [15] Schiffs bases [16 -19], chelating ionophores [20,21], thiophosphoril-containing macrocycles [22] and macrocyclic diamides [23]. However most of these Cu(II)-selective membrane suffer interfering effects from Co 2þ , Ni 2þ , Cd 2þ , Hg 2þ and Ag þ ions as well as limited linear ranges.…”

Novel PVC membrane (PME) and coated graphite (CGE) Cu 2þ -selective electrodes based on 5,6,7,8,9,10-hexahydro-2H-1,13,4,7,10-benzodioxatriazacyclopentadecine-3,11(4H,12H)-dione are prepared. The electrodes reveal a Nernstian behavior over wide Cu 2þ ion concentration ranges (1.0 Â 10 À7 -1.0 Â 10 À1 M for PME and 1.0 Â 10 À8 -1.0 Â 10 À1 M for CGE) with very low limits of detection (7.8 Â 10À8 M for PME and 9.1 Â 10 À9 M for CGE). The potentiometric responses are independent of the pH of the test solutions in the pH range 2.7 -6.2. The proposed electrodes possess very good selectivities for Cu 2þ over a wide variety of the cations including alkali, alkaline earth, transitions and heavy metal ions. The practical utility of the proposed electrodes have been demonstrated by their use in the study of interactions between copper ions and human growth hormone (hGH) in biological systems, potentiometric titration of copper with EDTA and determination of copper content of a sheep blood serum sample and some other real samples.

“…Macrocycles formed both by the aromatic and the heterocyclic units with three-coordinated phosphorus atoms as donors [3] are able to provide a variety of the donoracceptor and the non-valent interactions so they are of interest both for supramolecular chemistry (in particular as selective sensors [4] ) and as unusual ligands for transition metal catalyzed reactions in organic synthesis, [5] as the geometry and well-defined position of the complexing donor centers could lead to specific catalytically active complexes.…”
