Incorporation of Organic Counter‐Cations Into Poly(Heptazine Imide) Networks for Promoting Proton‐Coupled Electron Transfer During Photocatalytic H2O2 Evolution

open access: yesAngewandte Chemie, EarlyView.
Incorporation of N‐based onium ions into the ionic framework of poly(heptazine imide) was obtained via protonation‐deprotonation of PHI frameworks arising from a parent Na‐containing analogue. Particularly, methylammonium moieties, through their small molecular size, hydrogen bonding capabilities and rotational mobility, appear to stabilize ...

A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling

open access: yesAngewandte Chemie, EarlyView.
An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

open access: yesAngewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for

Ein chirales, sattelförmiges Nanographen mit zwei Heptagon‐integrierten [4]Helicenen

open access: yesAngewandte Chemie, EarlyView.
Wir präsentieren eine neuartige Synthesestrategie für ein chirales, sattelförmiges Nanographen (cSNG) über eine zweistufige Oxidation eines prochiralen Anthracen‐Vorläufers. Die Scholl‐Oxidation liefert zunächst ein Schlüsselzwischenprodukt mit sp3‐defekten Heptagonen, die anschließende oxidative Dehydrierung ergibt das vollständig konjugierte cSNG ...
