英文摘要	Molecular piezoelectrics are highly desirable for their easy and environment-friendly processing, light weight, low processing temperature, and mechanical flexibility. However, although 136 years have passed since the discovery in 1880 of the piezoelectric effect, molecular piezoelectrics with a piezoelectric coefficient d(33) comparable with piezoceramics such as barium titanate (BTO; similar to 190 picocoulombs per newton) have not been found. We show that trimethylchloromethyl ammonium trichloromanganese(II), an organic-inorganic perovskite ferroelectric crystal processed from aqueous solution, has a large d(33) of 185 picocoulombs per newton and a high phase-transition temperature of 406 kelvin (K) (16 K above that of BTO). This makes it a competitive candidate for medical, micromechanical, and biomechanical applications.; 973 project [2014CB932103]; National Natural Science Foundation of China [21290172, 91422301, 21427801, 21290170]; National Key Research Program of China [2016YF0300101, 2016YFA0201001]; SCI(E); ARTICLE; 6348; 357
