Diodelike Current–Voltage Curves for a Single Molecule–Tunneling Spectroscopy with Submolecular Resolution of an Alkylated, <i>peri</i>‐Condensed Hexabenzocoronene

Abstract

The electronic properties of molecules can in some cases be elucidated by scanning tunneling microscopy and spectroscopy. The current–voltage characteristics through the aromatic core of a benzocoronene molecule (1), localized with submolecular resolution, are the same those of a diode, and are caused by the properties of a single molecule in contact with two electrodes. R = n-C12H25.
