New preprint just dropped. The duo Yikun/Wojtek strikes again! We investigate multiply charged states of a conjugated porphyrin dimer, and discover that the unprecedented tetraanion has an open-shell character. As always, a great collab with @mpetrukhina.bsky.social chemrxiv.org/doi/full/10....

Knotting like a @natchem.nature.com cover! 😀 doi.org/10.1038/s415...

A new video in my serious about crystal structure refinement just dropped: disorder of COT radical anion about symmetry element! I recently collected data for this sample and thought it's quite good for teaching purposes. www.youtube.com/watch?v=2C5S...

Autonomous migration of a phosphate group along glycerol and inositol scaffolds driven by a phosphodiester reaction cycle #chemsky

Researchers at the University of Ulm have described the first autonomous walking small-molecule machine: a simple phosphate group. The walker travels along a hydroxy-paved molecular track using an alternating series of cyclization and ring-opening reactions. #chemsky 🧪
