After months of training, Ilayda, Annemarie and Alexandra walked 4x 40 km during the Nijmeegse Vierdaagse (Four Days Marches).

Encouraged by colleagues from the lab, who made a great sign 'Go Molecular Motors Go', they all made it to the finish line.

We are very proud! Well done!🏅

Chiral Induction and Memory via Supramolecular Deracemization The helical chirality of a dynamic crown-ether switch can, by light- or redox-switching to a prochiral state, be erased and subsequently stereoselectively re-formed by relaxation in the presence of a...

We’ve developed artificial muscles using a photoswitchable amphiphile that self-recovers after actuation—no external reset needed.
By tuning molecular motion, we link nanoscale assembly dynamics to macroscopic movement.
Think: light-powered, self-healing soft actuators.
Great work Adrien and Shaoyu!

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.

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.
