Congrats to @qingkaiqi.bsky.social @spatra18.bsky.social Heyifei & collab Xiaogang Liu’s group on our new @chemicalscience.rsc.org! 🎉 We show how solvent H-bond ability, donor number and water content control azo-BF₂ switch stability vs. 1,2-BF₂ shift/solvolysis. bit.ly/47gjjyv #chemsky ⚗️🧪
Solvent-dependent reactivity of azo-BF2 switches
Azo-BF2 complexes are visible and near-infrared (NIR) light-activated photoswitches showcasing versatility in applications ranging from energy storage to three-dimensional displays. While highly appea...

Congrats to Daniil for his publication in @chemcomm.rsc.org bit.ly/4l8B3jd showing how hydrazone photoswitches can be used in Raman scattering spectroscopy. A step forward for using hydrazones in super-resolution stimulated Raman scattering microscopy #molswitch #chemsky 🧪⚗️
Alkyne hydrazones for Raman scattering spectroscopy
We explored alkyne-functionalized hydrazone photoswitches and enhanced their performance, achieving improved UV resolution, higher photostationary states, and tunable alkyne shifts (up to 34 cm−1), es...

The 2016 Nobel prize in chemistry was awarded 'for the design and synthesis of molecular machines'. Ironically, we do not know exactly what constitutes a molecular machine. With the ultimate goal of unifying definitions and standardising terminology, Iupac needs your help!

Click chemistry is a powerful way to stitch molecules together — but in our new @jacs.acspublications.org paper bit.ly/4cNBqMK we find that not all triazoles are equal! When it comes to #photoswitch the 1,5-regioisomer (not from "click") surprisingly outperforms the classic 1,4🧪⚗️ #molswitch #chemsky
“Clicked” Hydrazone Photoswitches
The length of the linker connecting a photoswitch to a material significantly influences the latter’s properties, with “zero-length” linkers being ideal for optimal photomodulation. The 1,2,3-triazole...
