The detection of nerve agent simulants is achieved by the photoinduced electron transfer (PET) mechanism. A ‘‘turn-on’’ fluorescence response upon phosphorylation at 8-hydroxyquinoline of norbornene-based triazolyl functionalized 8-hydroxyquinoline (NCHQ) followed by intramolecular rearrangement provides very intense green emission. The detection limit of polymer (PNCHQ) coated paper strips is ...

The first examples of triarylboron-functionalized 8-hydroxyquinoline ligands and their aluminium complexes have been synthesized. These luminescent derivatives of the well-known electron transport material tris(8-hydroxyquinoline)aluminium (Alq(3)) display enhanced electron-accepting ability relative to Alq(3), and can also be used as an indicator for small F(-) and CN(-) anions.

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...

Pellets of paraffin wax implanted into the lumen of the bladder of 38 mice induced one carcinoma. An equally low incidence of carcinomas was induced with paraffin wax pellets containing 15-20 per cent suspensions of 8-hydroxyquinoline or quinaldic acid, 8-hydroxyquinaldic acid, xanthurenic acid, the 8-methyl ether of xanthurenic acid, 4,8-quinolinediol, L-kynurenine sulfate, 3-hydroxy-L-kynuren...

The detection of nerve agent simulants is achieved by the photoinduced electron transfer (PET) mechanism. A "turn-on" fluorescence response upon phosphorylation at 8-hydroxyquinoline of norbornene-based triazolyl functionalized 8-hydroxyquinoline () followed by intramolecular rearrangement provides very intense green emission. The detection limit of polymer () coated paper strips is 25 ppb with...

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...

Carnation (Dianthus caryophyllus L.) is valuable in terms of production and exports in the world. Increased vase life of cut flowers is an important factor for their market acceptability. For this purpose this study was carried out to examine the effect of plant essential oils as compared to 8-hydroxy-quinoline sulfate on the control of bacteria population and the longevity of carnation cut flo...
