Nature Chemistry
A monthly journal dedicated to publishing high-quality papers that describe the most significant and cutting-edge research in all areas of chemistry, reflecting the traditional core subjects of analytical, inorganic, organic and physical chemistry.
Highly conducting single-molecule topological insulators based on mono- and di-radical cations
Designing long and highly conducting molecular wires has been a great challenge for decades. It has now been shown that an oxidized 2.6-nm-long oligophenylene-bridged bis(triarylamine) can show a single-molecule junction conductance over 0.1G0.
In situ electro-synthesis and resynthesis of redox actives in aqueous organic redox flow batteries
We report in situ continuous anthraquinone electrosyntheses from lower-cost anthracene feedstock in a flow cell reactor to lower mass production cost of anthraquinone-based electrolytes, and in situ electro-resyntheses of active molecules from decomposed species to extend lifetime of aqueous anthraquinone redox flow batteries.
Nickel-catalyzed asymmetric hydrogenation of oximes
The asymmetric hydrogenation of oximes to chiral hydroxylamines is a long-standing problem due to the labile N-O bond and inert C=N bond. It has now been enabled by a chiral nickel catalyst with excellent results in which the weak interactions between catalyst and substrate play crucial roles.
Protein changes on the ultrafast timescale
In phytochrome Agp2 ultrafast proton-transfer occurs from the chromophore to a hydrogen-bonded water network in the protein prior to photoisomerization. The altered hydrogen bonds persist after photoisomerization and trigger together with the new chromophore geometry the activated protein conformation.
Cobalt(III) N-enolate carbene radicals with a protective function
Porphyrin ligand modification by acceptor-acceptor iodonium ylides is not necessarily a dead-end catalyst deactivation pathway, but can actually have a useful protective function by slowing-down deactivation pathways of the metalloradical cobalt(II)-tetraphenylporphyrin catalyst.
