Supramolecular nanofibers are formed from aqueous solutions of a bola‐ amphihile, containing two carboxylic end groups and a central π–π‐stacking moiety. The combined noncovalent interactions form the basis for the successful self‐assembly of the fibers. The obtained fibers (see figure), with widths on the nanometer scale and lengths of several micrometers or more, exhibit good thermal stability and interesting emittance properties.
