The regioselective carbonylation of indoles have attracted significant recent attention owing to the ubiquitous presence of indole derivatives in pharmaceuticals and natural products. Aldehydes are very appealing as effective carbonylation sources; however, methods to activate aldehydes toward successful incorporatio...

Vinylene-linked covalent organic frameworks (COFs) have attracted significant attention for their exceptional chemical stability and optoelectronic properties. However, the large-scale synthesis of vinylene-linked COFs remains challenging, as base- or acid-mediated solvothermal methods often result in uncontrolled crys...

Selective and green oxidation is a cornerstone of advancing sustainable chemical transformation. Conventional hydrogenation and dehydrogenation typically rely on stoichiometric oxidants or noble metals, operating under harsh conditions. To address these limitations, here, we present an efficient and recyclable photocat...

Woven covalent organic frameworks (woven COFs) represent a rare class of mechanically interlaced crystalline polymers whose synthesis is largely limited by the availability of suitable linkage chemistry. Herein, we report the first example of a vinylene-linked woven covalent organic framework, constructed through a K...

Designing efficient, metal-free covalent organic framework (COF) electrocatalysts is a promising strategy for the oxygen reduction reaction (ORR) due to their structural tunability and stability. Herein, we report two redox-active donor–acceptor COFs, TAPA-DHTD and TTT-DHTD, incorporating a thiophene-based dithiophened...
ABSTRACT Photocatalytic hydrogen peroxide (H2O2) generation via sunlight‐driven water and oxygen reduction reactions presents a sustainable alternative to the energy‐intensive anthraquinone process. Although metal–organic frameworks (MOFs) offer tunable platforms for photocatalysis, the influence of metal–ligand microe...
