Several 5-alkoxymethyl- and 5-aminomethyl-substituted 8-hydroxyquinolines were synthesised. Their coordination complexes with Al(III) were also synthesised. These complexes are soluble and stable in common organic solvents and show green luminescence with high quantum yields. (C) 2004 Elsevier Ltd. All rights reserved.
Effect of alkyl group position on adsorption behavior and corrosion inhibition of new naphthol based on 8-hydroxyquinoline: Electrochemical, surface, quantum calculations and dynamic simulations
The present investigation focused on the corrosion inhibition of mild steel in 1.0 M HCl medium by new naphthol based on 8-hydroxyquinoline. These products were characterized by 1H-NMRand 13C-NMR spectroscopy. The influence of concentration (C) and temperature (T) on the corrosion process of mild steel before and after addition of naphthol derivatives in corrosive solutions has been investigated through
