摘要: By scanning tunneling microscopy imaging and electronic structure theory, we investigate a single-molecule switch based on electron-driven rotation of triangular Sc3N cluster within an icosahedral C80 fullerene cage among three pairs enantiomorphic configurations. Bias-dependent action spectra modeling implicate the antisymmetric stretch vibration as gateway for energy transfer from electrons into rotation. Hierarchical switching conductivity multiple stationary states while maintaining constant molecular shape, offers advantage integration endohedral fullerene-based switches logic state devices.
