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👏👏👏

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: www.cell.com/chem/abstrac...

Transition-path times of individual molecular shuttles under mechanical equilibrium show symmetry: Chem www.cell.com/chem/fulltex... Molecular machines operate out of thermodynamic equilibrium, but as molecules in solution (low Reynold's number) are always in mechanical equilibrium.

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.

The achievement of unidirectional molecular movement is a significant challenge due to competition by Brownian motion. Nature can overcome this proble…

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 www.sciencedirect.com/science/arti...
