Aziridination of a Single Carbon Atom in Alkenes via Energy Transfer Catalysis

Angewandte Chemie International Edition, EarlyView.
Contrary to traditional alkene aziridination via (formal) nitrene transfer, we herein report a strategy that achieves intermolecular aziridination of a single alkene carbon atom and installs an additional group at the other. Enabled by metal‐free energy transfer (EnT) catalysis, alkenyl boronates and silanes are transformed into reactive intermediates ...

Re-design and evaluation of diclofenac-based carborane-substituted prodrugs and their anti-cancer potential

Scientific Reports
In this study, we investigated a novel anti-cancer drug design approach by revisiting diclofenac-based carborane-substituted prodrugs. The redesigned compounds combine the robust carborane scaffold with the oxindole framework, resulting in four carborane-

Chelating N-heterocyclic carbene-carboranes offer flexible ligand coordination to IrIII, RhIII and RuII: effect of ligand cyclometallation in catalytic transfer hydrogenation [PDF]

, 2016
Imidazolium salts linked by an ethyl tether to closo-dicarbadodecaboranes were reacted with [IrCp*Cl2]2, [RhCp*Cl2]2 or [Ru(p-cymene)Cl2]2 in the presence of Ag2O to prepare complexes of the type [MCp*(NHC)Cl2] (M = Ir, Rh; NHC = N-heterocyclic carbene ...

N‐heterocyclic carbene‐based tetradentate Pt(II) phosphors for blue organic light‐emitting diodes: Molecular design, photophysics, and device performance

Bulletin of the Korean Chemical Society, EarlyView.
Structure‐oriented design of NHC‐based tetradentate Pt(II) complexes offers narrowband deep‐blue emission for OLEDs. This review highlights how steric shielding and electronic modulation regulate intermolecular interactions, excited‐state dynamics, and device performance, outlining design principles and outlines toward efficient and durable blue ...

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Bright Solvatochromic Fluorophores With Dual Emission Enabled by a Donor‐Engineering Strategy

Chemistry – A European Journal, EarlyView.
We screened tertiary amines for installation on the donor unit of highly emissive donor–acceptor‐type solvatochromic fluorophores based on a 9,9‐dimethyl‐2‐phenyl‐9H‐fluorene scaffold, with the aim of enabling two bright emissive states to coexist. As a result, the azetidine derivative [4] and the azepane derivative [7] exhibited clear dual emission ...
