Transition stress management : The amphiphilic tris‐urea 1 was designed and synthesized as a low‐molecular‐weight gelator. The minimum gelation concentration of 1 is 1.9 m M . The hydrogel is thixotropic, and shows a reversible gel–sol phase transition in response to mechanostress. The amphiphilic tris‐urea 1 forms gels with various aqueous solutions, such as buffers and saturated NaCl, 8 M HCl, and 7 M KOH solutions. These hydrogels retain their thixotropic nature.
