Great project on the combined use of light- and redox-switching in hydrogels is now published in Nat. Commun. We can generate all types of stable redox patterns and actuation under ambient conditions using light for spatio-temporal control!

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.

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...

Another great collaboration with @sidlereric.bsky.social and @feringalab.bsky.social is now published in @angewandtechemie.bsky.social!

Very interesting!

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...

Cool thread, thanks! For JACS/ACIE I could definitely see all of these being factors and also think the citations point is relevant; there are soo many (new) journals these days it´s very difficult to keep track of everything and the high-impact "standards" are always an easy option to read/cite

Here a few more impressions:

Just returned from an awesome 3-week lecture/conference tour in Japan🗾 with stops in Kyoto, Fukuoka, Hiroshima, Osaka and Nagoya. Had an amazing time with great food, awesome people and inspiring science! Arigato gozaimasu!

Very nice!

Maybe chemically simple, but certainly not doing simple things 😄
Amazing how much there is to learn from these systems

Awesome, many congratulations!

Danke!

Thank you!

Thanks!

Vielen Dank und bis morgen!

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!

Thanks, took a while, but we found a very nice home for it now 😀

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.

This is a great initiative, I recommend everyone who is in the GDCh and interested in supramolecular chemistry to join!

Had a great time at this year's #Chemiedozententagung in Braunschweig! Looking forward to the next meeting in Essen

Even though I only had some small contributions to this work, this one is special to me, as it´s the last project to be published from my undergraduate research work! Actually, the investigation of cyclopentadiene dimerisation by CBs was the first project I ever worked on!

Hello bsky world! I also made the jump from the other platform and will be active here now. Happy to share a new publication on host guest chemistry:
"Regioselective Dimerization of Methylcyclopentadiene inside Cucurbit[7]uril" published in @chemistryeurope.bsky.social
doi.org/10.1002/chem...

Edit: In Chem Eur. J. this is definitely possible as well, we have done this in a recent publication (10.1002/chem.202302775). Maybe all/many Wiley journals allow this?

In Angewandte you can do this, but I don´t think it´s super common/mandatory yet. Am not aware of other journals where this is routinely done
