Mentions: Light-driven directional rotor 156 has been used todrive the macroscopic motion of a glass rod.1637,1638 When doped at 1 wt % into a liquid crystal, the helicity of therotor induced a helical arrangement in the liquid crystal, givingrise to a characteristic “fingerprint” texture in theliquid crystal’s surface. Irradiation altered the distributionof isomers of the rotor and thus caused the liquid crystal’shelical nature to rearrange. This process could be observed by theclockwise rotation it caused of a glass rod laid on the surface andof the “fingerprint” pattern. Eventually, however, rotationstopped as the system reached a photostationary state with the distributionof molecules between isomers reaching equilibrium. When the lightsource was removed, the isomer distribution decayed back to its initialstate, with concomitant reverse rotation. The use of the oppositeisomer of the rotor led to inversion of the direction of rotation(Figure 65).
