  • Self-healing organic crystals
    Patent number: 11872212
    Abstract: The invention provides non-centrosymmetric organic crystals which show exceptional self-healing properties. More particularly, the present invention provides non-centrosymmetric substituted imidazole and Dialkyl 4,4?-methylenebis(azanediyl)dibenzoate Crystals and a process for preparation thereof. These highly crystalline materials, when broken into pieces, can self-propel and re-join in the blink of an eye and repair themselves so precisely that they become indistinguishable from the undisturbed materials.
    Type: Grant
