Molecular Photogearing for Controlling Rotary Motion at the Nanoscale

open access: yesChemPlusChem, Volume 91, Issue 4, April 2026.
Molecular gears capable of controlling and transmitting rotary motion at the nanoscale are indispensable for the construction of artificial molecular machines. In this concept, we discuss how molecular photogears featuring a propeller‐shaped motif attached to a light‐driven molecular motor offer new possibilities to perform these tasks with better ...
