Electrogenerated chemiluminescence of the lithium salts of 8-hydroxyquinoline and 2-methyl-8-hydroxyquinoline.
The spectroscopy, electrochemistry, and electrogenerated chemiluminescence (ECL) of [(q)(qH)Li]x (qH=8-hydroxyquinolinato) and [(Meq)(MeqH)Li]x (MeQH=2-methyl-8-hydroxyquinolinato) have been investigated. In both acetonitrile and aqueous solutions, [(q)(qH)Li]x and [(Meq)(MeqH)Li]x have absorption maxima at 320 and 309 nm, respectively. When excited at these wavelengths, the complexes emit arou...
متن کاملFormation and Entrapment of Tris(8-hydroxyquinoline)aluminum from 8-Hydroxyquinoline in Anodic Porous Alumina
The formation and entrapment of tris(8-hydroxyquinoline)aluminum (Alq₃) molecules on the surface of anodic porous alumina (APA) immersed in an ethanol solution of 8-hydroxyquinoline (HQ) were investigated by absorption, fluorescence, and Raman spectroscopies. The effects of the selected APA preparation conditions (galvanostatic or potentiostatic anodization method, anodizing current and voltage...
متن کاملSome Aspects of 8-hydroxyquinoline in Solvents
The study of a UV-VIS spectrum of 8-hydroxyquinoline (8HQ) in different solvents can provide relevant information concerning the influence of the medium on the electronic structure of the solute or the nature and strength of the specific solvent-solute intraor intermolecular interactions. The electronic absorption spectra of 8-hydroxyquinoline in various solvents have very different features du...
متن کاملSpectrophotometric Determination of Tantalum(V) with 5-Iodo-8- -hydroxyquinoline-7-sulphonic Acid
Tantalum(V) reacts with 5-iodo-8-hydroxyquinoline-7-sulphonic acid to form a yellowish coloured complex having maximum absorbance at 405 nm in citric acid medium. The relatively slow reaction at room temperature is completed in 10 minutes at 40 °c. The colour is stable for at least 12 hr. Effects of heating temperature, time, pH, reagent concentration and other variables have been studied. The ...
متن کاملMicellar Liquid Chromatographic Determination of Aluminum Using 8-hydroxyquinoline-5-sulphonic Acid
A micellar liquid-chromatographic method is proposed for determination of Al(III) as the 8-hydroxyquinoline-5-sulfonic acid derivative, with spectrofluorimetric detection. Cetyltrimethylammonium bromide, a cationic surfactant (0.05 M), was used as mobile phase. The metal chelate was detected at λEx 410 and λEm 510 nm. Response to aluminum is selective in the presence of other metal ions. The me...
