Metal‐Enhanced Charge Transport and its Mechanism in Atomically Precise Ruthenium Single‐Molecule Devices

Advanced Science, EarlyView.
An atomically precise platform was developed for investigating single‐molecule charge transport. This innovative platform enables the creation of highly uniform molecular devices using ruthenium‐based molecules. It reveals a significant enhancement in molecular conductance due to the metallic ruthenium center and a unique barrier‐lowering effect during

Controlling Near‐Infrared Fluorescence‐to‐Phosphorescence Ratios and Triplet Lifetimes in Rhodium(I) Dimers via Primary and Secondary Coordination Sphere Effects

Angewandte Chemie, EarlyView.
RhI dimers with bridging aryl isocyanide and di‐phosphine ligands show NIR‐I or NIR‐II fluorescence/phosphorescence, depending on the ligands and conformational rigidity at the Rh2 core. Rh‐Rh interactions can be tuned by peripheral modification of the aryl isocyanide ligand, resulting in a rigid Rh2 core and improved photophysical properties ...

Synthetic Applications of the Parkins Nitrile Hydration Catalyst [PtH{(PMe2O)2H}(PMe2OH)]: A Review

Applied Sciences, 2015
The air-stable hydride-platinum(II) complex [PtH{(PMe2O)2H}(PMe2OH)], reported by Parkins and co-workers in 1995, is the most versatile catalyst currently available for the hydration of C≡N bonds.

High pressure synthesis of phosphine from the elements and the discovery of the missing (PH3)2H2 tile

Nature Communications, 2020
Chemical elements at high pressure may behave more consistently with their periodic properties than they do at ambient conditions. The authors report the synthesis of PH3 from black phosphorous and hydrogen, and the crystallization of the van der Waals ...

Cymantrene–Triazole "Click" Products: Structural Characterization and Electrochemical Properties [PDF]

, 2014
We report the first known examples of triazole-derivatized cymantrene complexes (η5-[4-substituted triazol-1-yl]cyclopentadienyl)tricarbonylmanganese(I), obtained via a “click” chemical synthesis, bearing a phenyl, 3-aminophenyl, or 4-aminophenyl moiety ...

Redox‐Active Tungsten Mono‐Oxo Bis(dithiolene) Complex: A Fast‐Rechargeable Anode for High‐Capacity Lithium‐Ion Batteries

Advanced Science, EarlyView.
This study reports the first application of a W‐oxo bis(dithiolene) complex, (Et4N)2[WO(S2C2(C6H5)2)2], as a novel anode material for lithium‐ion batteries. This complex stores Li+ ions via multivalent W‐centered redox processes involving its oxo (WO) and dithiolene (S) sites.

Ring‐Opening Arylation of Cyclic Diaryliodoniums via Cyclic Triaryliodanes as Aryne Precursors and Dynamic Aryl Reservoirs

Angewandte Chemie, EarlyView.
Cyclic diaryliodonium salts engage aryl Grignard reagents to trigger a self‐propagating aryne–arylation cycle. Transient cyclic triaryliodanes serve as aryne precursors and dynamic aryl reservoirs, delivering iodine‐capped teraryls with predominant meta‐selectivity. The preserved C─I bond enables outward π‐extension or inward recyclization.

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

Advanced Science, EarlyView.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
