Directional Second Sphere Effect on CO2 Activation and Reduction by Iron Porphyrin in Aprotic and Protic Media

Angewandte Chemie, EarlyView.
Directional control within the secondary coordination sphere redefines CO2 reduction by iron porphyrins. Simply rearranging identical urea hydrogen‐bond donors modulates reactivity, revealing that optimal catalysis does not only arise from maximal intermediate stabilization, but also from directional, adaptive non‐covalent interactions that balance ...

Tunable Synthesis of Multi‐Responsive NH‐Containing Helical Nanographenes With a Chiroptical Switching Function

Angewandte Chemie, EarlyView.
The Scholl reaction of 1,3,6,8‐tetrakis(oligophenyl)‐appended carbazoles afforded stable NH‐containing helical nanographenes, which showed significant redshift and reversible on/off switching of CPL upon the addition of base and acid, respectively. Furthermore, excited‐state proton transfer occurred in dimethyl sulfoxide to generate anionic species ...

Monitoring the Microwave Synthesis of d0‐Free Disordered Rocksalt Cathodes Using In Situ Infrared Pyrometry

Angewandte Chemie, EarlyView.
Despite its promise for producing metastable materials, the mechanisms underlying solid‐state microwave synthesis remain poorly understood. By combining in situ thermography with x‐ray diffraction and solid‐state NMR, this study uncovers a surprising order–disorder–order reaction pathway during the microwave synthesis of the Li1.1Mn0.9O1.9F0.1${\rm Li ...

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

Angewandte 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 ...
