Résumé en anglais : [en]
Two charge transfer complexes, namely [(BDAH)(+)(PA(-))] CT1 [(BTAH)(2+) (PA(-))(2)] and CT2 (BDAH = 1,2-benzenediamine, BTAH = 1,2,4,5-benzenetetramine, and PA(-) = 2,4,6-trinitrophenolate), were synthesized and fully ...
Lire la suite >Two charge transfer complexes, namely [(BDAH)(+)(PA(-))] CT1 [(BTAH)(2+) (PA(-))(2)] and CT2 (BDAH = 1,2-benzenediamine, BTAH = 1,2,4,5-benzenetetramine, and PA(-) = 2,4,6-trinitrophenolate), were synthesized and fully characterized using various spectroscopic techniques. CT1 and CT2 were tested as inhibitors to effectively control the uniform and anodic corrosion processes of copper in an alkaline electrolyte (1.0 M KOH) using various electrochemical techniques. As a reference point, results were compared with the potassium salt of the pi-acceptor potassium 2,4,6-trinitrophenolate (designated here as PA(-)K(+)). The highest inhibition efficiency (97%) was recorded for inhibitor CT2 at a concentration of 1.0 mM. The inhibition mechanism was discussed based on scanning electron microscopy and X-ray photoelectron spectroscopy results of the corroded and inhibited Cu surfaces. A theoretical study, based on quantum-chemical calculations of the synthesized compounds. performed by the DFF/B3LYP method with a 6-311++G(2d,2p) basis set by using Gaussian 09, Revision A.02 program, was also included to support experimental findings. The various quantum chemical parameters such as E-HOMO, E-LUMO, chemical hardness, and chemical softness of the investigated molecules were calculated, and their correlation with the inhibition efficiency of the synthesized compounds was discussed.
