Unlocking ferroelectricity in a metal-free adamantane derivative <i>via</i> targeted symmetry reduction
By introducing a symmetry-reduction design strategy in adamantane derivatives, overcoming the inherent high symmetry of globular molecules that typically hinders long-range electrical ordering, we report a metal-free ferroelectric 2-adamantylammonium bromide (2-ADAB) with a high Curie temperature of 383 K and robust polarization switching.
