The electrochemical property of 5-o-[N-(L-alanine)-ethoxy]phenyl-10,15,20-triphenylporphyrin(o-AlaNC 2-OTPP)and its zinc complexes(o-AlaN-C 2-OTPP·Zn)have been investigated with cyclic voltammetry in CH 2Cl 2 using TBPA as electrolyte.
The TG-DTG curve of a series of octaalkoxy naphthalocynine zinc complexes Zn(RO) 8NPc (NPc=C 48 H 16 N 8,R=C 4H 9,C 8H 17 ,C 12 H 25 ) and electronic absorption spectra of these complexes in different organic solvents are measured. The relation between structure and properties of these complexes are studied.
meso Tetrakis( p methoxyl)phenylporphyrin(T( p OCH 3)PP) and its Zn complex (Zn T( p OCH 3)PP) were synthesized and characterized by elemental analysis, 1H NMR, UV and fluorescence spectra. The electrochemical properties of the complex have been investigated by cyclic voltammetry, electrocapillary method in DMSO and a tentative mechanism of reduction on the mercury electrode has been proposed.
Meanwhile, the fluorescence lifetime of 2-[2-(9-ethyl-9H-carbazol-2yl)-vinyl]-quinolin-8-ol and its zinc complex showed long lifetime in benzene solution.
The corrosion and electrochemical behavior of CT3 steel and Armco iron in soft corrosive water at 20 and 80°C in the presence of a zinc complex with hydroxyethylidenediphosphonic acid (HEDPZn) and sodium nitrite and m-nitrobenzoate was studied.
A zinc complex of hydroxyethylidenediphosphonic acid (OEDP-zinc) is the most effective inhibitor of the anodic reaction.
This work is devoted to studying the passivating ability of the zinc complex of the 1-hydroxyethane-1,1-diphosphonic acid (HEDP) in a borate buffer solution.
Sorption of zinc complex ions from chloride solutions with ion exchangers
All results considered, make us conclude that the function of cyanide ions is not to form electroinactive zinc complexes, but to change the properties of difficultly soluble compounds formed on the cathode's interface in the course of electrolysis.
The interaction of meso-tetra(4-N-hydroxyethylpyridyl)porphyrin, meso-tetra(3-N-hydroxyethylpyridyl)porphyrin, and their zinc complexes with bovine serum albumin (BSA) was studied by electronic spectroscopy, CD, and equilibrium dialysis at pH 7.2.
Extra coordination of zinc complexes of bromo-substituted tetraphenylporphyrins was studied by spectrophotometry.
Dissociation of Zinc Complexes in a Series of Phenyltetrabenzoporphyrins with Varying Macrocycle Rigidity
Kinetic stability of zinc complexes with meso-phenyltetrabenzoporphyrins in DMSO-HOAc mixture and in glacial acetic acid was studied.
Zn complex with N-(4'-Benzo-15-crown-5)-2-(amino-N-tosyl)-phenylaldimine: Synthesis, crystal structure, and vibration spectrum
It was found that the catecholase activity of the Cu,Zn complex increased considerably upon immobilization on silica gel via hydrogen bonds and intercalation by ion exchange among the layers of montmorillonite.
The thermal stability of ATS is better than that of Ca-Zn complex and basic lead stabilizers, and equal to that of dibutyltin dilaurate.
The thermal stability of this product is better than that of Ca-Zn complex and basic lead salt stabilizers, and equal to that of dibutyltin diaurate.
The results show that decomposition takes place at 180°±5°C for lactic acid-Zn complex, 200°±5°C for EDTA-Zn, 240°±5°C for quinone-Zn and 190°±5°C for fulvic acid-Zn.
