ABSTRACT
The organic salt chlorocholine perchlorate [ClCH2 CH2 N(CH3 )3 â ClO4 ] (CCP) is found to be a molecular ferroelectric with a high theoretical spontaneous polarization (Ps) value up to 17.09â µC cm-2 . CCP exhibits two successive order-disorder phase transition at 332 and 365â K with space groups changing from Cc to Cmc21 and then P63 /mmc, accompanied by unusual two-step ladder-like dielectric, SHG signal with obvious "on/off" contrasts. These findingings provides a further instance of exploring successive thermal-stimuli multi-responsive switching materials applied as switches and sensors.
