• • Room-temperature ferroelectricity in an organic cocrystal was demonstrated (Wiscons et al., Angew Chem Int Ed, 2018, 57: 9044–9047), enabling practical applications without cryogenic constraints.
• • Replacing [BF4]− anions with larger bis(trifluoromethanesulfonyl)ammonium (TFSA) anions in host-guest inclusion compounds raises the Curie temperature (Tc) by increasing the transition energy barrier, as cited in the research text.
• • Order-disorder transitions in strained SrTiO3 (Salmani-Rezaie et al., Phys Rev Lett, 2020, 125: 087601) and KNbO3 (Tan et al., Inorg Chem, 2021, 60: 7961–7973) illustrate critical role of order-disorder behavior in ferroelectricity, informing design of organic systems.
• • Synergetic H-bonding and charge-transfer interactions in a self-assembled structure yield a room-temperature ferroelectric material with electric field-induced dipole switching and piezo/pyroelectric energy conversion (Deepak et al., Chem Mater, 2023, 35: 3316–3328), highlighting multifunctionality.
