Orientation Of Molecules

Abstract The orientation of molecules is crucial in many chemical processes. Here, we report how single dipolar molecules can be oriented with maximum precision using the electric field of a scanning tunneling microscope. Rotation is found to occur around a fixed pivot point that is caused by the specific interaction of an oxygen atom in the molecule with the Ag(111) surface. Both directions of rotation are realized at will with 100% directionality. Consequently, the internal dipole moment of an individual molecule can be spatially mapped via its behavior in an applied electric field. The importance of the oxygen-surface interaction is demonstrated by the addition of a silver atom between a single molecule and the surface and the consequent loss of the pivot point.

A method is presented for pico-Newton (pN) order force measurement using a carbon nanotube (CNT) probe, which is calibrated by electromechanical resonance. A CNT probe is constructed by attaching a CNT to the end of a tungsten needle or an atomic force microscope (AFM) cantilever using nanorobotic manipulators inside a field-emission scanning electron microscope (FE-SEM). Conductive electron-beam-induced deposition (EBID) is used for the fixation of CNTs with an internal vaporized precursor W(CO)6. For manipulating them easily and quickly, CNTs are dispersed in ethanol by ultrasonic waves and oriented on copper electrodes by electrophoresis. The elastic moduli of CNT probes are calibrated for use as a force measurement probe by electrically exciting at fundamental frequency. We analyzed the resolution of force measurement using a CNT probe. This force measurement can be used to characterize the mechanical properties of nanostructures and to measure friction or exfoliation forces in nanometer order.
