We were incredibly honored to welcome Dr. Isabel Torres from Mothers in Science to #UniversityofWarwick this week! Dr. Torres presented deeply insightful and frankly quite horrifying studies on the treatment of mothers in academia and how parenthood impacts STEMM careers. Great discussions!!

Agree! This summer feels like it's been especially crazy. We're peer reviewing ourselves to death!

This is one of those true jawdropping moments in science - absolutely crazy cool work from Michael and team 🤩

Science Magazine @science.org · Jul 31

This week in Science, researchers report an artificial molecular motor that can twist a molecular thread to form a mechanically interlocked molecule. The approach creates opportunities to fabricate mechanically interlocked molecules with precise structural control.

Massive thanks to you as well of course Spyridon, the editorial experience was awesome 😄😄😄

In addition to her paper being accepted (see other post), @anjaramstrom.bsky.social is also now on bluesky 🤩🎉🍀! Give her a follow if you like cool rotaxanes, there's some incredibly stuff from her brewing in the lab at the moment

Finally, huge thanks to the referees. This was an unusual referee experience in that referees were incredibly supportive and kind, yet offered detailed, extensive and highly valuable feedback. A true prime example of how good peer review is supposed to work 🤩

Also thanks to Eszter Borbas (Uppsala) who both helped us get the lanthankde spectroscopy right and let us use her machine, and to @sgoldup.bsky.social for developing muxh of the rotaxane chemistry we used and for great discussions helping improve the work

Thanks to Daisy for a massive amount of tricky computational work, undergraduate researcher Huseyn for great help with synthesis, to Monika for being mega helpful with the photochemical experiments and to Ste for loads of help with the computations and photochem. You guys rock!!

This was a complicated piece of research and I'm incredibly grateful to the team for their hard work. This is the first of many papers on metal chelate rotaxanes from the incredible talented @anjaramstrom.bsky.social - tag not in first post. Much more to come!!

Furthermore, the rotaxane could act as a sensor for transition metal ions. It binds several metals via the bipyridine units, but only Cu2+ induced a response in the luminescence - leafing to complete turn-off of any luminescence!!

Fredrik Schaufelberger @fschaufelberger.bsky.social · Jun 5

Through careful photochemical studies aided by Monika, she demonstrated that sensitization primarily occurs between the rotaxane components, and that this was due to through-space energy transfer. The compact nature of the rotaxane was key to this, as shown in simulations by Daisy and Ste.

In this paper, we show that the mechanical bond is a useful way to induce lanthanide luminescence. Lanthanides are highly luminescent, but only if sensitised by an adjacent chromosome, or "antenna". Anja made a rotaxane emitter where the lanthanide and antenna is separated via the mechanical bond

Modulation of Lanthanide Luminescence with the Mechanical Bond: Antenna‐Emitter Confinement in a Compact [2]Rotaxane

Luminescent emitters based on lanthanide ions are of ubiquitous importance in the biological sciences, but typically need sensitisation from a covalently attached adjacent chromophore – an “antenna” ....
