To the bursting point : The molecule shown forms a complex liquid‐crystalline phase in which core–shell columns are embedded in a polygonal honeycomb formed by supramolecular cylinders (see picture; R F =perfluorinated end groups). Temperature‐induced anisotropic swelling of the cylinders occurs, and a transition to a lamellar phase is induced by “bursting” of the cylinders at the theoretical limit of the circumference‐limited expansion.
