This paper reports on the experimental and theoretical studies of a light-driven micromotor, which is a “light mill” that rotates by absorbing photon energy. This light mill has four curved blades to form an axially asymmetric geometry. Upon lateral irradiation, the shape of the light mill induces an asymmetric photon heating to the surrounding gas molecules, leading to a gas convection that forces the light mill to rotate. The light mill was applied to actuate a scanning mirror for a laser… Expand

Light-powered micromotor driven by geometry-assisted, asymmetric photon-heating and subsequent gas convection
We report on the design, fabrication, and analysis of a light-driven micromotor. The micromotor was created from a nanoporous polymer with close-packed gold nanoparticles which generate heat byExpand
Photomechanics: Directed bending of a polymer film by light
It is shown that a single film of a liquid-crystal network containing an azobenzene chromophore can be repeatedly and precisely bent along any chosen direction by using linearly polarized light. Expand
Mechanical twisting of a guest by a photoresponsive host
This design concept, which significantly extends the successful coupling of motion beyond the intramolecular level seen in synthetic allosteric receptors, might allow for the remote control of molecular events in larger interlocked molecular systems. Expand
