Öğe Fluorescence properties and electrochemical behavior of some schiff bases derived from n-aminopyrimidine(Springer Nature, 2014-03) Gülcan, Mehmet; Doğrul, Ümit; Öztürk Ürüt, Gülsiye; Levent, Abdulkadir; Akbaş, EsvetA series of Schiff bases (L 1, L 2 and L 3 ) were prepared by refluxing aromatic aldehydes with N-Aminopyrimidine derivatives in methanol and ethanol. The structures of synthesized compounds were characterized by FTIR, 1H NMR, 13C NMR and microanalysis. The electrochemical behaviors of the Schiff base ligands were also discussed. Moreover, the evaluation of absorption and emission properties of the structures were carried out in five different solvents. The products show visible absorption maxima in the range of 304-576 nm, and emission maxima from 636 to 736 nm in all solvents tested.Öğe Synthesis, characterization, quantum chemical studies and electrochemical performance of new 4,7-dihydrotetrazolo[1,5-a]pyrimidine derivatives(SpringerLink, 2019-03-22) Akbaş, Esvet; Çelik, Savaş; Ergan, Erdem; Levent, AbdulkadirIn this study, 4,7-dihydrotetrazolo[1, 5-a]pyrimidine derivatives (1–5) were prepared via Multicomponent Cyclocondensation Reactions (MCRs). All structures were determined by using FT-IR, 1H/13C NMR and elemental analyses. The compounds were investigated as corrosion inhibitors using density functional theory (DFT) at the level of B3LYP/6-31G (d, p). According to the calculations, compound 1 appears to be a good inhibitor for corrosion. In addition, the electrochemical properties of the novel systems were investigated by CV.
