At the #EuregioDays2026, Alex qualified for the Euregio Young Researcher‘s Award - a fantastic opportunity to present his research on the degradation of SF6 to a jury of renowned scientists and politicians. After an inspiring day filled with inspiring discussions, he even won 3rd place! 📸 M. Sedlak

New paper alert! 🚨 In his first paper, Leon is kicking things off with NHO-functionalized bipyridines! High donor strength and proton-switchability make them excellent ligands for new (photo)functional materials and many more applications 💯 chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/...

NHO‐Functionalized Bipyridines: Proton‐Switchable Strongly Electron‐Donating Chelating Ligands

Decoration with N-heterocyclic olefins (NHOs) turns 2,2′-bipyridine into an electron-rich, proton-switchable ligand. The switching range is remotely tunable by the NHO backbone and can surpass the do...

ICPC was a blast! Had the best time discussing phosphorus chemistry and enjoying Montpellier with all you guys. And on top of that Franka even won best talk 🥳 Special thanks to @bearoy.bsky.social from @umontpellier.bsky.social and the whole organization team for hosting this great conference!

Bonjooour to all phosphorus lovers out there 🇫🇷 ICPC has officially started and the Dielmann group is of course also on board! Visit Alex‘ & Laura‘s posters on Mon 5:30 - 7:30 pm or come by the amphitheater Mousseron for Fabian‘s talk on Mon 3:30 pm and Franka‘s talk on Wed 10 am. See you there!

Ready for some peak coordination chemistry at the ICCC in Odense this week? We definitely are! Discover fascinating chemistry using linear carbon ambiphiles in Fabian’s talk on Wed, 9:25 in room K2 - or let Leon win you over for some highly donating bipy ligands in poster session 3 on Thu, 5-7 pm!

Excited to share that Alex won „Best Student Paper Award“ for his SF6 degradation paper 🥇 Truly deserved and wonderful to see that all the hard work pays off! www.nature.com/articles/s41...

True to tradition, we were back for the Innsbruck City Run relay 🏃🏃🏻‍♀️🏃🏻 🏃🏽 Extra kudos for Fabian, who absolutely crushed the 10K and finished 2nd place in his category 🥈 Thanks to everyone who made this such a well-organizied and fun event! #InnsbruckCityRun #UniversitätInnsbruck

New paper online 🥳 In Franka‘s 2nd paper she successfully synthesized 2 new isolable phosphonioacetylides 🤩 Check out pubs.acs.org/doi/10.1021/... for more details on the design principles and the resulting properties! Special thanks to @caputogroup.bsky.social for their supporting contribution 🤝

Isolable Phosphonioacetylides as Strong Neutral Carbon Donors with Variable Steric Demand and Tunable Donor Properties

Phosphonioacetylides are rod-shaped, neutral carbon donors with ambiphilic character at the terminal carbon. Despite their analogy to CO and isocyanides, they remain underexplored due to their high reactivity, and only one isolable free phosphonioacetylide has been reported. Here, we describe two new isolable, room-temperature-persistent examples stabilized either by two N-heterocyclic imines (NHIs) bearing bulky, flexible tert-octyl groups or by a single dipp-substituted NHI combined with alkyl substituents. Comprehensive characterization (SCXRD, NMR, IR, MS, DFT) confirms their strong donor properties and the accessibility of the reactive C2 unit. DFT analysis quantify how the substituents at phosphorus modulate the frontier molecular orbital energies, spanning a wide range of σ and π-donor strengths and π-acceptor abilities, with trends that mirror those of the corresponding phosphines. Both phosphonioacetylides readily form AuI complexes, whereas the less electron-rich compound shows the tendency to eliminate its C2 moiety thermally or upon hydrolysis. These results establish design principles for stabilizing and tuning phosphonioacetylides and open avenues for their use in coordination chemistry and catalysis.
