Comparative study of two spectrophotometric reagents for catechol analysis in guaraná seeds powder
(Sociedade Brasileira de Química, 2003)
New crown-ether Dibenzo-18-crown-4 ligand via sequential one-pot reaction
(2021-01-01)
A friendly synthetic rout for a new crown-ether was developed in this short communication. The method in question was able to produce the desirable product in high yields (up to 80%), even after some purification steps. ...
Gas Phase Structure and Reactivity of Doubly Charged Microhydrated Calcium(II)-Catechol Complexes Probed by Infrared Spectroscopy
(American Chemical Society, 2014-06)
Doubly charged microhydrated adducts formed from catechol and calcium(II) were produced in the gas phase using electrospray ionization (ESI) appearing as the most important ions in the mass spectra recorded. The gas phase ...
Antiprotozoal And Antioxidant Alkaloids From Alternanthera Littoralis

Detection of catechol using mixed Langmuir-Blodgett films of a phospholipid and phthalocyanines as voltammetric sensors
(Royal Soc Chemistry, 2010-01-01)
The combination of metallic phthalocyanines (MPcs) and biomolecules has been explored in the literature either as mimetic systems to investigate molecular interactions or as supporting layers to immobilize biomolecules. ...
Oxorhenium(V) Complexes with 2,3-Dihydroxynaphthalene
(WILEY-BLACKWELL, 2010)
2,3-Dihydroxynaphthalene (H(2)dhn) reacts with [ReOCl(3)-(PPh(3))(2)] or [ReOBr(3)(PPh(3))(2)] in a 1:1 molar ratio with formation of the isostructural complexes [ReOCl(2)(PPh(3))(2)(Hdhn)] (4) and [ReOBr(2)-(PPh(3))(2)(Hdhn)] ...
Immobilization of lutetium bisphthalocyanine in nanostructured biomimetic sensors using the LbL technique for phenol detection
(ELSEVIER ADVANCED TECHNOLOGY, 2011)
This study describes the development of amperometric sensors based on poly(allylamine hydrochloride) (PAH) and lutetium bisphthalocyanine (LuPc(2)) films assembled using the Layer-by-Layer (LbL) technique. The films have ...
