8-Hydroxyquinoline-based receptors 1-3, containing a trisubstituted triethylbenzene core, were prepared and their binding properties towards glycosides were evaluated. (1)H NMR and fluorescence titrations as well as binding studies in two-phase systems, such as dissolution of solid carbohydrates in apolar media and phase transfer of sugars from aqueous into organic solvents, revealed β- vs.α-an...

Aluminium tris(4-morpholinyl-8-hydroxyquinoline) has been synthesized and characterized. The photoluminescence measurements showed that the new derivative is blue shifted and has relative photoluminescence quantum yield two times higher compared to the pristine Al tris(8-hydroxyquinoline). Deferential scanning colorimetric studies revealed that the newly synthesized Alq3 derivative in this work...

Charge carrier dynamics in an organic semiconductor can often be described in terms of charge hopping between localized states. The hopping rates depend on electronic coupling elements, reorganization energies, and driving forces, which vary as a function of position and orientation of the molecules. The exact evaluation of these contributions in a molecular assembly is computationally prohibit...

The synthesis of the quinoline alkaloid atanine 6, by selective demethylation of the 2,4-dimethoxyquinoline 11 is presented. An alternative demethylation utilising a thiolate anion leads to the regioisomeric 4-hydroxyquinoline 13.

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...

A new hexadentate, tripodal 8-hydroxyquinoline ligand (QH3) and its trivalent metal chelates (MQ, M=Al3+, Ga3+, In3+) with hemicage structures have been prepared and the electrochemical and photophysical properties systematically studied. The hemicage structure of the metal complexes was characterized by 1H NMR, indicating a pure facial geometry, in contrast to their uncaged cousins with 8-hydr...

Two tetranuclear [Zn4Cl2(ClQ)6]·2DMF (1) and [Zn4Cl2(ClQ)6(H2O)2]·4DMF (2), as well three dinuclear [Zn2(ClQ)3(HClQ)3]I3 (3), [Zn2(dClQ)2(H2O)6(SO4)] (4) [Zn2(dBrQ)2(H2O)6(SO4)] (5), complexes (HClQ = 5-chloro-8-hydroxyquinoline, HdClQ 5,7-dichloro-8-hydroxyquinoline HdBrQ 5,7-dibromo-8-hydroxyquinoline) were prepared possible anticancer or antimicrobial agents characterized by IR spectroscopy,...

Quinoline was used to probe the steric and electronic contributions to rates of aromatic oxidation of nitrogen-containing, multiring substrates by cytochrome P450 (P450) enzymes. The regioselectivity of the P450 oxidation of quinoline was determined experimentally by identifying and measuring the ratios of metabolites. The laboratory results were compared with those obtained computationally by ...
