“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...

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

Electrochemistry of Azobenzenes and Its Potential for Energy Storage Azobenzenes are promising materials for energy storage due to their reversible photoisomerization and redox properties. Given the critical role of redox behavior in the latter application, an investigation of their redox processes is essential. We propose a classification of azobenzenes into two categories: benzenoid-type and quinoid-type, based on the mechanism of their oxidation. Benzenoid-type compounds have been extensively studied due to their reversible reduction. Quinoid-type compounds exhibit oxidative and reductive versatility, making them promising for further research in energy storage.
