  • Molecular recognition is an important biological process where guest and host molecules interact through non-covalent bonding. Yeet al. show that this can be sensed by the dielectric and ferroelectric signals of the final complexes in a series of metal-coordination compounds with different diol molecules.

  • Molecular ferroelectric crystals hold promise in data storage applications, yet their preparations by maximizing molecular polarization are challenging. Here, Youet al. report quinuclidinium periodate with six rotation axes and grow them in macroscopic ferroelectric thin films via a solution process.

  • Two-dimensional materials can present ferroelectricity by layer sliding, but electrical confirmation is lacking due to narrow bandgaps. Here, a single-crystal coordination polymer with large bandgap enabling direct electrical measurement of P–E hysteresis is shown to present sliding ferroelectricity.

  • Ferroelectric phase transitions are normally accompanied by structural changes in the materials. Here, Li et al. synthesize homochiral molecular crystals and utilize their ferroelectric transitions to achieve optical switches with different refractive indices for left- and right-handed polarizations.

  • A semiconducting molecular ferroelectric (2-(ammoniomethyl)pyridinium)SbI5 was designed. It shows an above-room-temperature Curie temperature (Tc=360 K), a large spontaneous polarization (Ps=4 μC cm−2) and small bandgap (2.03 eV) that are comparable to those of the well-known semiconducting ferroelectrics BiFeO3 (Eg=2.7 eV) and SbSI (Eg=2.0 eV). The implementation of ferroelectricity into hybrid semiconducting materials will move the applications of hybrid semiconducting molecular ferroelectrics in optoelectronic and photovoltaics devices forward.
