Check out our latest paper on efficacy photoswitches that can locally light up opioid receptors, thus avoiding unwanted central and peripheral side effects (respiratory depression, constipation). Great collaboration with Levitz (Weill Cornell), @CorneliusGati (UCX) and @sevakat1 (USC) cell.com/cell/fulltext/S0092…

Our AM-3 paper is out in Cell. Opioids are critical drugs, but have severe side effects. Because they are administered systemically, it is hard to dissect how they work, and to separate side effects. So we built one you can switch on and off with light. cell.com/cell/abstract/S0092…

I am thrilled about the Nobel Prize for Optogenetics. Congrats to Peter, Georg, and Karl! And I’m happy that the Nobel committee correctly portrayed the role Chemistry played in the development of this field: nobelprize.org/uploads/2026/…

Feeling down? Reviewer 3 was nasty? 13C-NMR doesn’t match? TLC shows an Autobahn? Tomorrow is another day. And our “Need Motivation” button is back! traunergroup.org

Amazing Lineup this Fall!
I've been dabbling a lot with @Claude coding and wanted to modernize the POCC website (again). In doing so we've added a ton of new features to the site and were able resurrect a lot of lost records. We've also added modern tools like calendar integration etc, go check it out!

Be sure to check out the new-and-improved POCC website for details about upcoming events, like next month's seminar, at pocclub.org!

Check out our preprint on “azostitching”, a one-pot synthesis of azobenzenes and azoheteroarenes from organoboron compounds and anilines. This modular method vastly expands the accessible chemical space of azo dyes and photoswitches, opening new possibilities for their exploration in materials science, chemical biology, and photopharmacology. chemrxiv.org/doi/10.26434/ch…

Stephadiamine, take two. A second synthesis is justifiable if you (a) radically change the strategy and (b) develop new methodology along the way. Congratulations, Ana Vi, on bringing this one home! pubs.acs.org/doi/full/10.102…

Silyl protecting groups can function as dispersive directing groups , leading to unusual stereoselectivities! Collaborating with @bobbypaton, we have demonstrated this for a specific case. Stay tuned for a more systematic study! pubs.acs.org/doi/full/10.102…
