A Metal‐Free Molecular Ferroelectric With Large Piezoelectricity and Its Porous Composite for Superior Output Power Density

Advanced Science, EarlyView.
Metal‐free molecular crystal [(CH3C6H10NH3)(18‐crown‐6)][ClO4] functions as a high‐performance molecular ferroelectric. Through strategic methylation of the cyclohexylamine unit, the compound achieves large spontaneous polarization and outstanding piezoelectric coefficients.
