Rotary cycle of the new, more efficient light-driven motor molecule (IMAGE)
Caption
Depiction of the structural changes during 4-step unidirectional isomerization of 1st generation aldehyde motor with key features above the reaction arrows. Starting from top left, UV light induces photoisomerization to reach the top-right state with more than 95 percent efficiency. This top-right state transforms by a unidirectional thermal ‘helix inversion’ step (THI) to the version depicted bottom right, completing a half cycle of the rotation. Subsequent UV irradiation will lead to the formation of state depicted bottom left (with over 80 percent efficiency), which can transform to the initial state of the motor by another unidirectional THI step, finishing the 360o rotation cycle.
