#Catenane
Our latest work, led by group alumnus Youzhi Xu is dedicated to the memory of Fraser Stoddart! In May, I asked him about his favourite molecule made in his lab. After a while, he said: the "Olympiadane" ABCBA-type [5]catenane. @damabilino.bsky.social #chemsky

Ring‐in‐Ring Assembly Facilitates the Synthesis of a [12]Cycloparaphenylene ABC‐Type [3]Catenane
By threading a secondary ammonium salt through the crown ether and closing the third ring via CuAAC click reaction, we obtained a rare ABC-type hetero-[3]catenane comprising [12]CPP, 24-crown-8 and a...

In @science.org this week, Harry Anderson's group finally put their cyclic carbon allotrope into solution. The, well, solution to getting it there? Protection by catenation--have a look!

A circular molecule made up of just 48 carbons has been stabilised using macrocycles. This has allowed this kind of normally fleeting carbon allotrope to be bottled and investigated

The researchers worked with now late Nobel laureate Fraser Stoddart on the new strategy, which they say could act as inspiration to the pharmaceutical and materials science industries.

I get to say “catenane” and “decatention” pretty much every day and it’s delightful

Fantastic first work by former group member Youzhi Xu at Henan U!👇 It is hard enough to make a hetero[3]catenane. They did it in 35% yield via "ring-in-ring synthesis" from two commercial macrocycles😮!!! We were very happy to help with MS-MS studies. #chemsky

A simple mathematical model has been used by chemists to create interwoven catananes. Greater control over the synthesis process could allow scientists to produce more complex interlinked molecules.
