On the move: Irradiation of azobenzene-doped liquid crystalline films with UV/Vis light results in the photocontrolled translational motion of microscale solid object on the surface, which occurs through cis-trans isomerization of the azobenzene unit. Irradiation with an Ar(+) laser (488 nm) resulted in precise control of the translational motion so that the particle always moved away from the irradiation position (see picture).
用紫外/可见光照射偶氮苯掺杂的液晶薄膜会导致表面上微尺度固体物体的光控平移运动,这是通过偶氮苯单元的顺反异构化发生的。用氩离子激光(488纳米)照射可精确控制平移运动,使粒子总是远离照射位置(见图)。
