Abstract Widely used polyzwitterionic hydrogels usually suffer from significant mechanical loss, owing to the strong hydration of zwitterionic groups. Herein, a novel solvent polarity‐induced strategy is introduced for developing pure supramolecular organogels with ultrahigh strength by using facile one‐pot synthesis process. The properties these can be well‐tuned adjusting polarity dihydric alcohol solvents regulate hydrogen bonding and dipole‐dipole interactions between polymer chains in organogel network. exhibit superior properties, including tensile 1.5 MPa, elongation at break 669%, toughness 3.2 MJ m − 3 , adhesive 506 kPa. Additionally, display outstanding impact response performance (maximum strain‐stiffening ratio 140 times, maximum impact‐stiffening 450 times) energy dissipation (energy above 60%, loss factor 2.0 1 Hz), resulting presence inter‐molecular internal friction. Notably, synergistic groups on side organic impart flexibility vibration absorption capabilities even low‐temperature environments. Furthermore, demonstrate flaw‐insensitivity, self‐healing ability, water processability, broadening their applicability more complex conditions.
