Considering how often his name still comes up, even in the most random settings, it’s difficult to believe that he is no longer with us. RIP, Fraser #chemsky #chemchat

Remembering the great Fraser Stoddart, especially today a year after his death, and all those who miss him. Here in Nottingham in 2017 at the Golden Age of Chemistry meeting.

Interesting lecture from matthieu in SIOC today! @msollogoub.bsky.social

Dynamic start of day 2 at #JCO2025 @scf-dco.bsky.social with a spectacular lecture of Matthieu Sollogoub @msollogoub.bsky.social @ipcm-sorbonne.bsky.social showing the many shapes of Cyclodextrins.

Happy to share this cover finally online in the September issue of chem. Thank you @vivesgui.bsky.social and @msollogoub.bsky.social for the design and drawing of such nice cover👏👏👏

Our work on the unidirectional motion of a CD is now in the September issue of Chem and on the cover!
Many thanks to the whole team and @cp-chem.bsky.social for the highlight!

We take advantage of the mechanical equilibration to explore the details of the mechanical motion which, in the presence of chemical energy input can drive the formation of a non-equilibrium steady state - see SI and very recent paper:

Not going back: Unidirectional movement by intramolecular one-way ratcheting of functionalized cyclodextrin Achieving unidirectional molecular movement is a major challenge, often requiring molecular ratchets. Here, we exploit the unique 3D structure and selective functionalization of cyclodextrin to achieve unidirectional motion in a rotaxane system. The cyclodextrin enables one-way gate opening and promotes forward movement via a double-gated ratchet mechanism. These findings pave the way for more efficient rotary molecular motors in cyclic systems and could enable long-range translational motion at the molecular scale.

Not going back: Unidirectional movement by intramolecular one-way ratcheting of functionalized cyclodextrin The achievement of unidirectional molecular movement is a significant challenge due to competition by Brownian motion. Nature can overcome this proble…

More than happy to share this work on the unidirectional movement of a functional cyclodextrin on an axle in Chem @cp-chem.bsky.social ‬ ! Congratulation to @enxuliu.bsky.social and all the team!!! www.sciencedirect.com/science/arti... @ipcm-sorbonne.bsky.social @sorbonne-universite.fr

Excited to share our latest work now out in Chem! A functionnalized CD that moves unidirectionally by actively opening the way in only one direction. Huge thanks to @enxuliu.bsky.social and the team! @ipcm-sorbonne.bsky.social @msollogoub.bsky.social
