Supramolecular electronics is the experimental field of supramolecular chemistry that bridges the gap between molecular electronics and bulk plastics in the construction of electronic circuitry at the nanoscale.{{Cite journal |last1=Meijer |first1=E.

With single molecules as researched in molecular electronics at the 5 nanometer scale this would be impractical.{{why|date=November 2023}} Nanofibers can be prepared from polymers such as polyaniline and polyacetylene.{{Cite journal |last1=Schenning |first1=Albertus P.
