Paper Abstract

Light-driven micro-particles (MPs) were prepared by modification of photo-responsive azobenzene(Azo) groups as molecular motors. In a nematic liquid crystal, 5CB, we have achieved remote control of the Azo-modified MPs (Azo/MPs), which constructed with glass spheres (GSs) or rod-like glass particles (GRs) as MPs, by light stimuli. As results of photo-induced isomerization from UV-visible extinction spectroscopy and from phase evaluation under microscope observation, the motion behavior suggest to be correlated with the generation of micro-sized isotropic phase (I-phase) regions, which could be caused by disorganization of the 5CB molecules in the nematic phase (N-phase) due to photo-induced continuous isomerization of Azo groups.
