Barbarian aggregates : A barbituric acid‐functionalized quarterthiophene self‐aggregates in aliphatic solvents to form nanorods. Upon addition of a bismelamine receptor, the nanorods are converted into nanotapes, which can be thermally reconverted to nanorods. Nanorods and nanotapes self‐organize into hexagonal columnar and multilamellar structures with high hole mobilities (see figure).
