Achievement of a giant electromechanical conversion coefficient in a molecule-based ferroelectric.

ABSTRACT: Molecule-based ferroelectrics are promising candidates for flexible self-powered power supplies (i.e., piezoelectric generators (PEGs)). Although the large electromechanical conversion coefficients (d ₃₃ × g ₃₃) of piezoelectrics are key to enhancing the performance of PEGs in their nonresonant states, it remains a great challenge to obtain molecule-based piezoelectrics with large d ₃₃ × g ₃₃. Here, we report a molecule-based ferroelectric [(CH₃)₃NCH₂CH₂Cl][GaBr₄] (1) that exhibits the largest piezoelectric coefficient (∼454 pC N^-1) and electromechanical conversion coefficient (4953.1 × 10^-12 m² N^-1) among all know
