Gelling together : The alternate coassembly of a noncovalent donor–acceptor (D–A) amphiphilic pair in water results in very long nanofibers that form hydrogels (see scheme). Microscopic and single‐crystal studies have provided an insight into the hierarchical self‐assembly of the charge‐transfer (CT) amphiphile, which consists of coronene and a viologen derivative, into cylindrical micelles and gels as the concentration of the D–A pair is increased.
