Controlling the morphology of supramolecularnanostructures in response to external stimuli is an important challenge in the development of functional soft materials. Here we show that a morphologicaltransformation from 2D nanosheets to a network of 1D nanofibers is triggered by heating, which induces molecular conversion of a bolaamphiphile to a hydrogelator by means of a retro‐Diels–Alder reaction, thereby
