New aspects of the Ni(II)-salophen complex and salophen ligand precursor were found during deep electrochemical and optical characterization, as well as biological studies for new pharmacological applications. Physicochemical and spectroscopic methods (1H- and 13C-NMR, FT-IR and UV-Vis, electrospray ionization mass spectroscopy, thermogravimetric analysis, and molar conductance measurements) were also used to prove that the salophen ligand acts as a tetradentate and coordinates to the central metal through nitrogen and oxygen atoms. The electrochemical behavior of the free Schiff salophen ligand (H2L) and its Ni(II) complex (Ni(II)L) was deeply studied in tetrabutylammonium perchlorate solutions in acetonitrile via CV, DPV, and RDE. Blue films on the surfaces of the electrodes as a result of the electropolymerization processes were put in evidence and characterized via CV and DPV. (H2L) and Ni(II)L complexes were tested for their antimicrobial, antifungal, and antioxidant activity, showing good antimicrobial and antifungal activity against several bacteria and fungi.

“…29 The illustrated potentiometric anion selectivity arrangement, that's deviated from the Hofmeister scheme. [30][31][32][33][34][35][36][37][38][39] Those deviations result of selective interchange among the ionophore and the analyte anion. Bis [4-hydroxyacetophenonesemicarbazonenitrato] nickel(II) as an ionophore has synthesized for the estimation of thiocyanate ion.…”

A novel highly-selective potentiometric sensor based on aquadichloro(E)-2-((1-(thiophen-2-yl)ethylidene)-amino)phenol manganese(II)trihydrate as an anion carrier was developed. The thiocayanate electrode displayed a very high selectivity compared with others inorganic anions. Different sensors with plasticized PVC membranes have been investigated. The sensor's construction contains different amounts of ionophore with and without additives. The pH over 3.56.5 range has been studied. The optimized membrane electrode included 66 mg PVC, 132 mg o-nitrophenyloctylether, 10 mol % tetrakis(trifluoromethyl)phenyl borate, and 2% [Mn(C12H11NOS)(Cl2)(H2O)]. 3H2O. The optimized sensors exhibited Nernstian response for thiocyanate through a linear concentration ranging from (5  10-8 to 9.06  10-3 M) with a detection limit of 3 ×10-8 M and a slope of -57.7 mV/decade, the measurement carried out in acetate buffer pH 4.7. The response time of the electrode was 10 s and the life time of the sensor was more than six weeks. The proposed electrode was effectively utilized for estimation of thiocyanate in saliva samples; the results revealed a valid agreement with reference colorimetric method.
