Check out the most colourful work of my PhD, available now from Nature Communications! (It's open access, you have no excuse not to read) Thank you to my collaborators, among others @robertheinchem.bsky.social @feringalab.bsky.social www.nature.com/articles/s41...

An international team of scientists including Jun.-Prof. Marcel Rey from @uni-muenster.de has developed laser driven microgears. For the first time, movable gears smaller than a hair's diameter were presented, breaking the former threshold of 0.1 mm. www.nature.com/articles/s41...

Another great collaboration with @sidlereric.bsky.social and @feringalab.bsky.social is now published in @angewandtechemie.bsky.social! Building on our previous work, Eric prepared large, formally antiaromatic pi-systems with interesting (chir)optical and redox properties: doi.org/10.1002/anie...

Indeno[2,1‐c]fluorene Quasi[8]circulenes Through Intramolecular Cyclization

A new class of curved, chiral polycyclic aromatic hydrocarbon emerges from the fusion of indeno[2,1-c]fluorene and quasi[8]circulene motifs. These redox-active, antiaromatic scaffolds offer great syn...

Very happy to announce that I got a little upgrade; as of this month I am Juniorprofessor of Organic Chemistry @uni-muenster.de! Very grateful for all the support from my group, colleagues and also for additional funding from the state of NRW via a Return Fellowship!

Just published in @jacs.acspublications.org, our project @feringalab.bsky.social on responsive crown ethers! Redox-switching? Light-switching? Why not both and get the best of all worlds, including guest shuttling, pseudorotaxanes, cascades and (non)volatile states. pubs.acs.org/doi/10.1021/...

Multi-State Redox and Light-Driven Switching of Pseudorotaxanation and Cation Shuttling

The modulation of molecular recognition underpins numerous wide-ranging applications and has inspired the development of a myriad of switchable receptors, in particular photo- or redox-responsive hosts. Herein, we report a highly versatile three-state cation receptor family and switch system based on an overcrowded alkene strapped with crown ethers, which can be switched by both redox and light stimuli, thereby combining the advantages of both approaches. Specifically, the neutral switches can be quantitatively converted between anti- and syn-folded receptor geometries by irradiation, leading to the discovery of a significant increase or decrease in cation binding affinity, which was exploited to shuttle the pseudorotaxane-forming dibenzylammonium guest between the switchable crown ethers of slightly different sizes. Alternatively, two-electron oxidation to the orthogonal, dicationic, nonvolatile state completely turns off cation binding to the host, thereby ejecting the guest. Upon reduction, the metastable syn-folded state is first formed, which then thermally relaxes, resulting in a unique, autonomous, and cation-dependent multistate switching cascade.
