Meet the molecules of the year 2025
C&EN editors’ annual round-up of spectacular molecules we’ve covered in the past year
cen.acs.org
And the molecule of the year for 2025 is...🥁...
...hexanitrogen! (I had a feeling this one would win 🤭)
Thanks for voting, everyone! #chemsky

I think it says a lot about the current moment that we chose molecule that is surprisingly holding itself together despite a thermodynamic incentive to break down...
We asked, you voted! Hexanitrogen is your 2025 Molecule of the Year! To get all the details on the spectacular finalists, check out our full coverage at cen.acs.org/synthesis/Mo...

While the financial landscape didn’t change much for biotechnology and pharmaceutical companies this year, the geopolitical forces shaping the industry did. So did the technological ones. Here is C&EN’s look back at the past year. cen.acs.org/pharmaceutic... #chemsky 🧪
C&EN’s Year in Pharma 2025
In some ways, the pharmaceutical world simply plodded along this year. In others, it was stood on its head

A few weeks ago, I went on a podcast and said I didn't know anyone who was doing skeletal editing with boron. Then I read this paper and learned that (a) these guys did it before it was cool and (b) now they're using boron to do even more interesting stuff to molecular cores!
The 1,2-oxaborine scaffold can be converted into a variety of different aromatic rings with relative ease, enabling chemists to vary molecular cores while keeping the peripheral groups mostly the same. cen.acs.org/synthesis/sh... #chemsky 🧪
These shape-shifting rings create customizable cores
