Photocatalytic Solar Hydrogen Peroxide Production on Donor+Acceptor Linear Polymer Semiconductor Powders Reconfigurable by H‐Bonding and π‐Stacking Interactions

Angewandte Chemie International Edition, EarlyView.
A linear polymer, poly(2,3‐dihydroxynaphthalene), when insolubilized, leads to self‐assembly into a hydroquinone–quinone donor+acceptor semiconducting architecture through H‐bonding and π‐stacking interactions. The polymer behaves as a heterogeneous photocatalyst in water for H2O2 production via water oxidation and O2 reduction under visible light.

Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Controlling the Guanidinium Cation Rotation by Cation–π Interactions

Angewandte Chemie International Edition, EarlyView.
A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.
