Gas Phase Structure and Reactivity of Doubly Charged Microhydrated Calcium(II)-Catechol Complexes Probed by Infrared Spectroscopy [PDF]

open access: yes, 2014
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 structures of [Ca(catechol)2(H2O)

NMR spectra and electrochemical behavior of catechol-bearing block copolymer micelles

open access: yesData in Brief, 2015
Here, we provide the NMR spectra and AFM data for antioxidant micelles prepared from amphiphilic PAM-PDA block copolymers composed of a poly(N-acryloyl morpholine) and a redox-active catechol-bearing block with different catechol content. We also provide

Characterization and evaluation of catechol oxygenases by twelve bacteria, isolated from oil contaminated soils in Malaysia [PDF]

open access: yesBiological Journal of Microorganism, 2017
Introduction: Catechol is a common intermediate compound in aromatic degradation process. Some microorganisms have this potentiality to degrade aromatic hydrocarbons by catechol dioxygenases to less toxic compounds with ability of entering the ...

The catalytic role of uranyl in formation of polycatechol complexes

open access: yesChemistry Central Journal, 2011
To better understand the association of contaminant uranium with natural organic matter (NOM) and the fate of uranium in ground water, spectroscopic studies of uranium complexation with catechol were conducted.

From catechol‐tocopherol to catechol‐hydroquinone polyphenolic antioxidant hybrids

open access: yesHeteroatom Chemistry, 2018
AbstractMultidefence antioxidants represent a valuable solution for the protection against oxidative stress. From the planned synthesis of a catechol‐tocopherol hybrid, we isolated a catechol‐hydroquinone hybrid through a BBr3‐mediated benzochromene‐fluoren‐1‐ol transposition.

A Computational and Spectroscopic Approach to Elucidate the Coordination Structures in Iron–Catechol Polymers

open access: yesChemistry Proceedings
Coordination polymer particles (CPPs) with catechol functionalities present significant potential for various applications. To elucidate their structural features, we synthesized CPPs using bidentate bis-catechol and catechol–pyridine ligands and ...
