Abstract
The simple organic salt chlorocholine perchlorate [ClCH2CH2N(CH3)3 ·ClO4] (CCP) is found to be a molecular ferroelectric with a high theoretical spontaneous polarization (Ps) value up to 17.09 μC cm-2. CCP could undergo two successive order-disorder phase transition at 332 and 365 K with space group changing from Cc to Cmc21 and then P63/mmc, accompanying with unusual two-step ladder-like dielectric, SHG signal with obvious "on/off" contrasts. This finding provides a new instance of further exploring successive thermal-stimuli multi-responsive switching materials applied as switches and sensors.
