Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks
Angewandte Chemie International Edition, EarlyView.A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Towards hydrogen and halogen bonded frameworks based on 3,5-bis(triazolyl)pyridinium motifs
, 2022 We attempted to use hydrogen, iodo and seleno 3,5-bis(triazolyl)pyridinium (btp) motifs to form 3D supramolecular frameworks assembled by hydrogen, halogen or chalcogen bonding to anions.

Metal-Free Aziridination of Unactivated Olefins via Transient N-Pyridinium Iminoiodinanes
We describe a metal-free aziridination of unactivated olefins to generate N-pyridinium aziridines, which participate in cross-coupling to afford N-aryl aziridines and reductive depyridylation to afford N–H aziridines.

Bis(4,4′-bipyridin-1-ium) cis-bis(1,2-dicyano-2-sulfidoethene-1-sulfinato-κ2S,S′)platinate(2−)
IUCrDataCrystals of the sulfinate-containing platinate salt, (C10H9N2)2[Pt(C4N2O2S2)2], were obtained from a solution of [Pt(4,4′-bpy)2(mnt)] after a long period with minimal light (4,4′-bpy is 4,4′-bipyridine and mnt is maleonitriledithiolate). In the crystals,

Porous Carbon Materials for Carbon Dioxide Capture
Carbon Energy, EarlyView.This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
