“…Therefore, no ion exchanger was employed in this study. The neutral carrier‐based cation‐selective membranes are usually functional without the incorporation of anionic sites . EMF measurements of these ISEs based on tetraazaannulene derivatives 1–4 were carried out by increasing the CuCl 2 concentration.…”

“…For example, the ISE based on a cyclam derivative with two benzene rings incorporated into the carbon atoms of the cyclam backbone exhibited good ion‐selectivity for the Cu 2+ ion . Moreover, ISEs based on a cyclam derivative with four 2‐pyridylmethyl groups attached on nitrogen atoms as substituents also showed good ion‐selectivity for the Cu 2+ ion . ISEs based on cyclam derivatives have thus been developed as cation sensors .…”

[14]Tetraazaannulene derivatives 1–4 with various substituents were synthesized as ion recognition compounds. All solvent polymeric membrane electrodes incorporating [14]tetraazaannulene derivatives 1–4 showed rapid response for the Cu2+ ion and exhibited excellent selectivity over other mono‐ and divalent cations such as Ag+ and Ni2+ ions. The solvent polymeric membrane electrode based on [14]tetraazaannulene derivative 1 has a linear response to the Cu2+ ion from 5.01 × 10−7 – 2.63 × 10−4 M with a slope of 29.56 mV per decade. DFT calculations showed that the selectivities for the Cu2+ ion of the ISEs based on [14]tetraazaannulene derivatives 1–4 depended on both their topological and electrostatic properties caused by the introduced substituents.

“…Until now, only a few metal complexes with coordinated tpmc have been synthesized [15][16][17][18][19][20][21], mostly with copper(II) ions, in dinuclear complexes [22][23][24]. These complexes have shown different electrochemical properties [25,26], as well as antibacterial [4,17] and cytotoxic activity [19,27,28]. According to our knowledge, this is the first report of the synthesis, characterization, and electrochemical and biological study of a dinuclear zinc complex with tpmc containing nitrato ion as a bridging ligand, as well as a dinuclear nickelnitrato complex with tpmc ligand.…”

Two new nitrato complexes of zinc and nickel with 1,4,8,11-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc), have been synthesized and characterized. The IR spectral peaks showed that the coordinated and ionic nitrate ions are in agreement with the formula proposed by elemental analysis. Conductometric titrations predicted methanol to be a convenient solvent for synthesis and revealed the stoichiometry of the complexes, while molar electrical conductivities indicated a 1 : 3 complex electrolyte type for the zinc complex, and a 1 : 2 complex electrolyte type for the nickel complex. The optimized complex structure was obtained by molecular modeling and density functional theory calculations. The biological activity of the novel complexes was examined by screening eight different bacterial strains and two cancer cell lines. The zinc complex showed better antimicrobial activity against the bacterial strains, while the complexes did not show significance antiproliferative activity toward cancer cells MCF-7 and MDA-MB-231.

“…This is the reason why a lot of copper-selective sensors based on different ionophores were reported. Several organic compounds, such as: 1-(2-hydroxybenzylidene) thiosemicarbazide [7], Schiff bases [8,9], 2-mercaptobenzoxazole [10], bezo-substituted macrocyclic diamide [11], 6-methyl-4-(1-phenylmethylidene)amino-3-thioxo-1,2,4-triazin-5-one [12], porphyrin derivatives [13], cyclic tetrapeptide derivatives [14], 7-hydroxy-3-(2-methyl-2,3-dihydrobenzo[d]thiazol-2-yl)-2H-chromen-2-one [15], tetraazacyclotetradecane derivative [16], dimethyl 4,4’-( o -phenylene)bis(3-thioallophanate) [17], succinimide derivative [18], polyindole [19] were tested as ionophores.…”

BackgroundCopper is an essential trace element with a great importance in industry, environment and biological systems. The great advantage of ion-selective sensors in comparison with other proposed techniques is that they are measuring the free metal ion activity which is responsible for their toxicity. Porphyrins are known to be among the best ionophores in formulation of ion-selective sensors.ResultsA symmetrically substituted meso-porphyrin, namely: 5,10,15,20-tetrakis(4-allyloxyphenyl)porphyrin (TAPP) was used in the construction of a new copper selective-sensor and was also tested for the removal of copper from waste waters. The potentiometric response characteristics (slope and selectivity) of copper-selective electrodes based on TAPP in o-nitrophenyloctylether (o-NPOE), dioctyl phtalate (DOP) and dioctyl sebacate (DOS) plasticized with poly(vinyl chloride) membranes are compared.ConclusionsThe best results were obtained for the membrane plasticized with DOP. The sensor has linear response in the range 1x10-7 – 1x10-1 M with 28.4 ± 0.4 mV/decade near-Nernstian slope towards copper ions and presents good selectivity. Due to its chelating nature, the same porphyrin was also tested for the retention of copper from synthetic copper samples, showing a maximum adsorption capacity of 280 mg/g.
