✦ Synopsis

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. For more information, see the paper by J. R. Heath, D. F. Perepichka et al. on page 2914 ff.
