Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

Advanced Science, Volume 13, Issue 37, 3 July 2026.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

Mechanistic Insight into H2S‐Induced Fluorescence Quenching in a Robust Metal–Organic Framework

Small, Volume 22, Issue 39, 13 July 2026.
An ultramicroporous Zn‐based metal‐organic framework, MFM‐520, enables reversible hydrogen sulfide adsorption and selective fluorescence sensing. Confinement of H2S within the pores perturbs ligand‐centered excited states through weak host‐guest interactions, enhancing non‐radiative decay pathways.

Crystal structure of 2-(5-methoxy-1-benzofuran-3-yl)acetic acid

Acta Crystallographica Section E: Crystallographic Communications, 2015
The benzofuran residue in the title compound, C11H10O4, is essentially planar (the r.m.s. deviation for the nine non-H atoms = 0.011 Å). While the methoxy group is coplanar with the fused ring system [C—C—O—C torsion angle = 3.1 (3)°], the acetic acid ...

Rh(III)‐Catalyzed [4+2] Annulation of Imidazoles With α‐Diazocarbonyl Compounds: Direct Access to π‐Conjugated Imidazole‐Fused Isoquinolinone

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H
