Controllability of coercive stress in organoferroelasticity by the incorporation of a bulky flipping moiety in molecular crystals

The control of coercive stress in organoferroelasticity is demonstrated in single crystals of trans-1,4-cyclohexanedicarboxylic acid with bulky cyclohexane rings. Flipping difficulty, due to the bulkiness, increased coercive stress, which can improve mechanical damping. Crystals also undergo the spontaneous disappearance of a twinned domain upon unloading before the completion of domain formation.
