Motors consisting of a single molecule that can produce useful work from energetic input will be vital for the future synthesis and operation of nanomachines. Simple biaryl molecules that can undergo unidirectional dihedral rotation should show promise for application in this area. These asymmetric molecules should be capable of channeling chemical and light energy into repeated 360 degree rotation in one direction. Recent progress in the synthesis and characterization of these biaryl molecules, as well as evaluation of their motor properties, will be presented.
