The role of diads … in molecular electronics has been investigated with the recently synthesized tetrathiafulvalene‐σ‐trinitrofluorene diad (depicted on the cover). As determined by cyclic voltammetry, the HOMO–LUMO gap of this diad is as low as ∼0.3 eV, close to that of the theoretical Aviram–Ratner TTF‐σ‐TCNQ molecular rectifier. The rectification behavior of this molecule was tested as a function of electrode material (Si/Ti and Au/Hg), alignment, and orientation of the molecules in the junction.
