Reversibility of the shape deformation. a The DSC curve during the α- to β-phase transformation. The dashed lines are the baseline for the integration of the exothermic and endothermic peak. The same integral value indicates a completely reversible phase transition. Source data are provided as a Source Data file. b The reversibility of the macroscopic deformation, as measured by the reversible changes of the corner angles of the crystal, from 92° to 103° and from 88° to 77°, respectively, for over 100 heating/cooling cycles. c Schematic diagram of the molecular conformational changes during the phase transition. Rotation of the phenyl rings (gray segments) with respect to the rigid center part of the molecule (red and blue segments) leads to different corner angles
