Center of attention : Multifunctional platinum/lithium cobalt oxide (Pt/LiCoO2) heterostructures are prepared that allow the active center to be switched between Pt species for the hydrogen evolution reaction (HER) and LiCoO2 species for the oxygen evolution reaction (OER). Abstract Designing cost‐effective and efficient electrocatalysts plays a pivotal role in advancing the development of electrochemical water splitting for hydrogen generation. Herein, multifunctional active‐center‐transferable...

A biocatalytic photoelectrochemical platform for solar‐assisted dual biotransformations is constructed by wiring a Mo‐doped BiVO4 photocathode and a hierarchical porous ITO electrode. The deliberate integration of enzymatic redox processes into the photoelectrochemical cell simultaneously facilitates peroxygenase‐ and ene‐reductase‐mediated enantioselective synthesis of high‐value chemicals using solar‐powered electrons and water. Abstract Inspired by natural photosynthesis, biocatalytic...

An iridium dihydride pincer complex [IrH 2 (POCOP)] is immobilized in a hydroxy‐functionalized microporous polymer network using the concepts of surface organometallic chemistry. The introduction of this novel, truly innocent support with remote OH‐groups enables the formation of isolated active metal sites embedded in a chemically robust and highly inert environment. The catalyst maintained high porosity and without prior activation exhibited efficacy in the gas phase hydrogenation of ethene and...

Nanosheets meet nanodots : A novel covalent assembly strategy is proposed for MoS2 nanosheets to realize unique MoS2/SnS hollow super‐assemblies by using SnS nanodots as covalent linkages. The strategy enables effective across‐interlayer electron transfer, facilitated ion diffusion kinetics, and high mechanical stability for high‐performance electrochemical lithium/sodium storage. Abstract Weak van der Waals interactions between interlayers of two‐dimensional layered materials result in...

To d or not to d : Ferrocene complexes of Ca, Sr, and Ba show clear evidence for Fe⋅⋅⋅metal bonding while no such interaction is present in the Mg complex. Analysis with the QTAIM and EDA‐NOCV methods points to Fe→Ae bonds that involve vacant d‐orbitals of alkaline‐earth metals. Abstract Double deprotonation of the diamine 1,1′‐(t BuCH2NH)‐ferrocene (1 ‐H2) by alkaline‐earth (Ae) or EuII metal reagents gave the complexes 1 ‐Ae (Ae=Mg, Ca, Sr, Ba) and 1 ‐Eu. 1 ‐Mg crystallized as a monomer...

A new class of partially pyrolyzed NiFe metal–organic framework nanosheets (MOF NSs) was created for the electrochemical synthesis of H2O2 by two‐electron oxygen reduction reaction (ORR) for the first time. The optimized MOF NSs‐300 exhibits the highest activity for ORR with near‐zero overpotential and excellent H2O2 selectivity (ca. 99 %) in 0.1 m KOH, outperforming most electrocatalysts reported to date. Abstract Herein, we developed a partially controlled pyrolysis strategy to create...

The switch : Combined XPS, STM, and local work function measurements verify that the charge states and locations of potassium species on monolayered CuO films can be reversibly switched by polarity‐reversed STM bias voltage pulses. Abstract Potassium (K) cations are spontaneously formed upon thermal deposition of low‐coverage K onto an ultrathin CuO monolayer grown on Cu(110) and they were explored by low‐temperature scanning tunneling microscopy (STM) and X‐ray photoemission spectroscopy....

The Rb7Sb3Cl16 phase , comprised of isolated octahedra and edge‐shared dimers, demonstrates photoluminescence centered at 560 nm with a quantum yield of 3.8 % at 296 K (99.4 % at 77 K) and a specific temperature sensitivity above 0.06 K−1 at 300 K. Utilizing DFT and chemical substitution with Bi3+ in the Rb7Bi3−3x Sb3x Cl16 (x ≤1) family, the [Sb2Cl10]4− dimer is presented as a design principle for Sb‐based luminescent materials. Abstract Low‐dimensional ns2‐metal halide compounds have...

Divergent enantioselective total syntheses of five naturally occurring post‐iboga indole alkaloids, dippinine B ( 3 ) and C ( 4 ), 10,11‐demethoxychippiine ( 8 ), 3‐ O ‐methyl‐10,11‐demethoxychippiine ( 9 ), and 3‐hydroxy‐3,4‐secocoronaridine ( 11 ), and two analogues 11‐demethoxydippinine A ( 2 ) and D ( 6 ), were presented for the first time. The enantioenriched aza[3.3.1]‐bridged cycle, common core intermediate to the target molecules, was constructed through an asymmetric phase‐transfer‐catalyzed...

DNA nanostructures have shown potentials in cancer therapy. However, current clinical practice is hampered by the difficulty to deliver them into cancer cells and susceptibility to nuclease degradation. To overcome these limitations, we report herein a periodically‐ordered nick‐hidden DNA nanowire (NW) with high serum stability and active targeting functionality. The inner core is made of multiple‐connected DNA double helices and the outer shell is composed of regularly‐arranged standing‐up hairpin...

Carbonyls reconciled : Electrostatics and orbital interactions have both been implicated in governing carbonyl interactions. A combined experimental and computational approach reconciles these conflicting explanations of the physiochemical origin of the interaction, demonstrating that orbital delocalisation augments electrostatic control, but for very close carbonyl contacts. Abstract Interactions between carbonyl groups are prevalent in protein structures. Earlier investigations identified...

A Mn‐catalyzed diastereo‐ and enantioselective asymmetric hydrogenation of α‐substituted β‐ketoamides was realized by using lutidine‐based chiral PNN ligands via a dynamic kinetic resolution to afford optically active anti‐α‐substituted β‐hydroxy amides in high yields with excellent stereoselectivity (up to >99 % dr and >99 % ee ). The anti stereoselectivity is ascribed to an attractive π⋅⋅⋅π stacking between the substrate phenyl and ligand pyridyl rings. Abstract A Mn‐catalyzed...

The unstrained carbon–carbon bond of an aryl ketone can be activated by a Pd‐catalyzed ligand‐promoted β‐carbon elimination reaction. In this way, aryl ketones can be transformed into useful aryl borates, and also to biaryls, aryl nitriles, and aryl alkenes. The utility of this strategy was demonstrated by the late‐stage diversification of several drug molecules. Abstract The coupling of aromatic electrophiles (aryl halides, aryl ethers, aryl acids, aryl nitriles etc.) with nucleophiles...

A complex twist : A highly electron‐rich N‐heterocyclic carbene stabilized 1,2‐divinyldiborene, which displays no delocalized π conjugation because of twisting of the C2B2C2 chain, coordinates to CuI and Pt0 in a η2‐B2 and η4‐C2B2 mode, respectively, while undergoing a complex rearrangement to a η4‐1,3‐diborete upon complexation with Ni0. Abstract The reductive coupling of an N‐heterocyclic carbene (NHC) stabilized (dibromo)vinylborane yields a 1,2‐divinyldiborene, which, although isoelectronic...

It takes two : A highly efficient propargylic alkylation reaction was developed that delivers high yields with excellent enantiomeric ratios through dual Ni/Cu catalysis (up to 99 % ee ). This Ni/Cu bimetallic system provides a reliable and a versatile approach for the development of a wide range of useful stereocontrolled reactions. Abstract A novel Ni/Cu dual catalysis gives rise to fundamentally new cooperative reactivity and enables the regio‐ and enantioselective propargylic alkylation...
