A new organic-inorganic hybrid perovskite ferroelectric, [ClCH2CH2N(CH3)3][PbBr3] (CEPbBr) was obtained by the reaction of (2-chloroethyl) trimethylammonium chloride [ClCH2CH2N(CH3)3]+Cl- with lead (II) bromide in HBr aqueous solution. CEPbBr could undergo a...

Organic-inorganic hybrid rare-earth double perovskite has been paid more and more attention owing to their intriguing chemical and physical properties. In this paper, we report a new layered 2D hybrid...

The organic salt chlorocholine perchlorate [ClCH 2 CH 2 N-(CH 3 ) 3 •ClO 4 ] (CCP) is found to be a molecular ferroelectric with a high theoretical spontaneous polarization (Ps) value up to 17.09 μC cm À 2 . CCP exhibits two successive order-disorder phase transition at 332 and 365 K with space groups changing from Cc to Cmc2 1 and then P6 3 /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.[a] D.
