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.
Synthesis of Aryldifluoromethyl Aryl Ethers via Nickel-Catalyzed Suzuki Cross-Coupling Reactions
An efficient synthesis of aryldifluoromethyl aryl ethers was established via nickel-catalyzed aryloxydifluoromethylation. Using this protocol, difluoromethylated PD-1/PD-L1 immune checkpoint inhibitors were comveniently achieved with enhanced antitumor efficacy over the non-fluoro congeners.
Long-chain hydrocarbons from carbon dioxide using polarized nickel electrocatalysts
Until now, only copper catalysts possessed a distinctive feature: the ability to form multicarbon products at appreciable rates. Copper is not alone anymore. We discovered that polarized nickel enables C1 to C6 hydrocarbons via a Fischer-Tropsch-like mechanism with selectivities up to 6.5% for C3+.
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.
Bis-Schiff base linkage makes gold nanoclusters brighter
We develop an efficient strategy to increase the photoluminescence quantum yield of water-soluble gold clusters at the single-cluster level via formation of bis-Schiff base linkages, and its mechanism is deeply investigated.
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.
