| Research Abstract |
The present study aims at realizing organic molecular motors driven by spin injection based on the principle of the Einstein-de Haas effect. To drive the molecular rotation from the tunneling current from the scanning tunneling microscope (STM) tip and simultaneously observe it by STM, it is essential to introduce a rotational axis against the molecule. We have found that a spontaneously created single-atom impurity on the herringbone structure of Au(111) surface plays the role of the axis, and that a Pt-porphyrin molecule preferentially adsorbed on this site works as a rotor. The molecule was found to exhibit reproducible rotations on this axis.
