| Research Abstract |
Previous studies on liquid crystal systems containing impurities such as colloidal particles have focused on the collective long-range interactions among micron-scale impurities, resulting from elastic distortion of the liquid crystalline order. Here, we propose a novel mechanism in which the spatial variation of S generates a 'force' that transports nano-scale solutes mediated by the coupling between S and solute concentration. We have successfully designed a prototype of a molecular manipulator that transports a molecular solute along spatial variations of the scalar order parameter, modulated in a controlled manner by spot illumination of an azobenzene-doped nematic phase by UV light. The manipulator can control the spatial variation of the polymer concentration; therefore it shows promise for use in the design of novel hybrid soft materials.
