How does Near-Infrared-Photoswitching work? Our newest research delivers an ultrafast molecular movie of the all-red-light photoswitch peri-Anthracenethioindigo (PAT) in action! Aided by excited state theory, its mechanism of motion is fully revealed.

Excited State Dynamics of Odd [n]Cumulenes: Chain Length and Conformational Effects Over the past decades, carbon allotropes have been extensively studied and applied to various technological applications due to their unique electronic and optical properties. Contemporary research ha...

Years in the making, finally published! Congrats Bob and Yanwen, and thanks for the great collaboration ‪‪@guldi-group.bsky.social‬!

Reversible gating of singlet fission by tuning the role of a charge-transfer state - Nature Communications Singlet fission is an efficient way to generate excitons but is rarely responsive to external stimuli. Here the authors design a linked tetracene dimer where acid/base interactions can control singlet...

We are pleased to announce that our latest Nature Communication article on singlet fission (doi.org/10.1038/s414...) was selected in the Editors’ Highlights webpage!

Had a fantastic week of measurements at @mpip-mainz.mpg.de — thanks a lot to @giulialavarda.bsky.social for hosting me. Honored to be the first guest of her group!

Really enjoyed learning about THz spectroscopy in the group of Prof. Bonn. And many thanks to Prof. Blom for the fruitful discussions!

Was great connecting with you all in beautiful Burlington House @rsc.org ! @guldi-group.bsky.social @chemguyeli.bsky.social and many more. To the next years to come!😊

Chemische Reaktionen: Mit Hochdruck entschlüsselt Sie bilden die Basis vieler grundlegender Prozesse des Lebens. Ohne sie könnten weder Zellatmung noch Photosynthese stattfinden. Redoxreaktionen spielen aber auch für Anwendungen in der Chemie…

When optical features miss excited-state PCET, environmental effects step in. We show that pressure not only reveals mechanistic sensitivity but can even switch the reaction from stepwise to concerted.
Big congrats to Daniel!
