Abstract

Electronic devices at the single-molecule level (<3 nm in all directions) may provide the fastest possible electronic components, whose excited states would decay by photons, while comparably sized Si-based components must decay by phonons, and require enormous heat dissipation methods. Progress in unimolecular rectification is reviewed, with particular emphasis on the two possible ground states (Zwitterionic or quinonoid) of quinolinium tricyanoquinodimethanide, which depend crucially on intermolecular forces. Other lively issues (metal– organic interface, future three- and four-probe devices) are briefly introduced.
