Abstract: We report a spatially resolved scanning tunneling spectroscopy (STS) investigation of reversibly switchable dipolar vanadyl phthalocyanine (VOPc) on graphite by using low temperature scanning tunneling microscopy. VOPc molecule can be switched between O-up and O-down configurations by changing the polarity of the pulse voltage applied to the tip, actuated by the inelastic tunneling electrons. The spatially resolved STS measurements allow the identification of the electronic structures of VOPc with different dipole orientation. The present approach provides geometry images and electronic characterization of a molecular switch on surface spontaneously. © 2014 AIP Publishing LLC.
