Tuning Antiaromaticity Through Meso‐Substituent Orientation in Core‐Modified Isophlorins

Asian Journal of Organic Chemistry, EarlyView.
The antiaromaticity of dithiadioxaisophlorins is controlled by the steric bulkiness of meso‐substituents through their tilt angle relative to the macrocycle. Bulkier substituents maintain larger angles, preserving stronger antiaromaticity, while smaller groups facilitate π‐conjugation with the macrocycle, diminishing antiaromaticity.

Rotlicht‐vermittelte Erzeugung von Radikalen: Anwendung in Organischer Synthese, Aktivierung kleiner Moleküle, Polymerisierungen und Bio‐bezogener Fachbereiche

Angewandte Chemie, EarlyView.
Die mit sichtbarem Licht betriebene Photochemie hat erhebliche Fortschritte gemacht und bietet vielfältige Methoden für die synthetische organische Chemie. Die Photokatalyse mit rotem und nahinfrarotem‐Licht (NIR) ist aufgrund der geringeren Energie, der reduzierten Phototoxizität, der minimierten Nebenreaktionen und des tieferen Eindringens in ...

Fast Seawater Desalination Driven by Efficient Nitrate Reduction via Bimetallic Iron/Zinc Polyphthalocyanine Frameworks

Angewandte Chemie, EarlyView.
Bimetallic Fe/Zn polyphthalocyanine frameworks enable highly efficient and selective electrochemical reduction of nitrate to ammonia. When integrated into an electrocatalytic desalination device, this reaction facilitates rapid salt ion mass transfer, allowing the conversion of natural seawater into drinkable water and simultaneously converting nitrate

Mechanistische Promiskuität bei der Cobalt‐vermittelten CO₂‐Reduktionsreaktion: Ein‐ Versus Zwei‐Elektron‐Reduktionsprozess

Angewandte Chemie, EarlyView.
Die Cobaltkomplexe [(Hbbpya)CoII]2⁺ und [(Mebbpya)CoII]2⁺ zeigen unterschiedliche CO₂‐Reduktionsmechanismen. [(Hbbpya)CoII]2⁺ bildet selektiv CO über einen schnellen, Zwei‐Elektronen‐Mechanismus, der durch ein –NH‐Protonentransfer unterstützt wird, während [(Mebbpya)CoII]2⁺ die Wasserstoffentwicklung bevorzugt, aufgrund eines langsameren, kompetitiven ...
