Give and take: X- or H-shape superamphiphiles form on the basis of directional charge-transfer complexes and lead to the formation of one-dimensional nanorods and two-dimensional nanosheets, respectively (see picture, blue: pyridinium ion, red: naphthalene derivatives, green: naphthalene diimide). The superstructures form after elaborate tuning of the building block structures.
