A Persistent Open-Shell m-QDM-Type Diindenoanthracene Diradicaloid with a Large Diradical Character | Journal of the American Chemical Society
pubs.acs.org
Indenofluorenes (IFs) have received great interest owing to their intrinsic antiaromaticity, open-shell diradical character, and narrow band gaps. Herein, we report the synthesis and comprehensive...

Science & Wine goes well together. We hosted Mike Haley @UOHaleyLab for a Seminar and a PhD tutorial talk at @ChemUniCologne. He concluded on his journey on antiaromaticity, before we hiked the Ahrtal for some concentraded red wines. Thanks Mike! @prince_ravat @UniCologne

Happy to share that our latest result have been published in @angew_chem Congratulations to all team!! @borylation @cycloBODIPY @YoshiTsuchido @HisakiLab [3]CycloBODIPY: A Highly Strained Cyclic BODIPY Trimer with Effective Macrocyclic Conjugation
onlinelibrary.wiley.com
A macrocyclic [3]cycloBODIPY, composed solely of boron-dipyrromethene (BODIPY) units, was synthesized via gold-mediated cyclization. Despite its high strain energy (86.4 kcal mol−1), flexible boron...

Bold hypothesis, thorough study, and fundamentally on point. THIS is exactly the major challenge in the field: bistable + photoswitchable + paramagnetic. Congratulations @JuricekLab Wonderful molecular system, Pauline, Daniel, Tamara!
Interested in non-functional organic magnetic switches? We actually do want to make them work — that’s why we study the ones that don’t, so we can make them function :-) Check out our new preprint 🔗 https://t.co/EOmPPIi42T

Never thought I would develop new protective groups. Great collaboration with the group of Birgit Esser @Besserchemistry on making PTO more soluble and develop milder deprotections. @ChemUniCologne
Working with pyrenetetraones (PTOs)? Check out our new protective group strategy to facilitate their syntheses! As a joint venture with @DumeleLab, we present a simple solution to some preparative difficulties of using PTOs in functional materials.
