Photocatalytic Aqueous Reforming of Methyl Formate

Advanced Materials, EarlyView.
A 3d‐metal Cu‐based atomically dispersed photocatalyst, supported on modified g‐C₃N₄, facilitates the photocatalytic selective hydrogen (7.5 mmol gcat−1 of hydrogen; nothing else than H2 and CO2) generation from methyl formate. This diverse system functions under mild conditions, providing high hydrogen yield, selectivity, and enduring stability ...

Confining Quantum Dots Within Covalent Organic Framework Cages for Coupled CO2 Photoreduction and Value‐Added Chemical Synthesis

Advanced Materials, EarlyView.
A 3D/0D S‐scheme heterojunction photocatalyst is constructed by spatially confining ZnSe quantum dots within covalent organic framework (COF) porous cages, enabling coupled CO2 photoreduction and value‐added chemical synthesis. COF porous cages serve as nanoreactors, enriching reactant concentrations, and the S‐scheme heterojunction facilitates charge ...

Unlocking Spin Dynamics: Spin‐Orbit Coupling Driven Spin State Interconversion in Carbazole‐Containing TADF Emitters

Advanced Optical Materials, EarlyView.
This study explores overlapping charge transport mechanisms in TADF materials and identifies spin‐orbit coupling as the dominant mechanism for triplet‐to‐singlet transition in carbazole‐based cyanoarene emitters. Computational investigations reveal a second spin‐orbit‐coupling‐mediated reverse intersystem crossing pathway, significantly enhancing the ...

Visible‐Light‐Promoted Dearomatization for The Construction of Imidazole Scaffolds

Advanced Synthesis &Catalysis, EarlyView.
Lighting up flat aromatics: a visible‐light photocatalytic dearomative acylation of imidazo[1,2‐a]pyridines using α‐keto acids as sustainable acyl radical precursors is reported, leading to dual fluorescent imidazoles. Dearomatization is a powerful strategy for constructing complex carbocycles and heterocycles, though it typically relies on harsh ...

One‐Pot Cascade Synthesis of Isoquinolinone‐Fused Quinoxalines Through Sequential Rh(III)/Pd(II) Catalysis

Advanced Synthesis &Catalysis, EarlyView.
A new one‐pot, dual catalytic strategy for the synthesis of polycyclic isoquinolinone‐fused quinoxalines from commercially available N‐(2‐acetamidophenyl)benzamides and 1,3‐diynes is reported. This transformation proceeds via Rh(III)/Pd(II)‐mediated sequential NH/CH activation/annulation. Detailed mechanistic studies elucidate the reaction pathway. A
