WebMay 12, 2024 · Molecular chirality is generally caused by the construction of the chiral center; thus, introducing the chiral center has been a conventional method for molecular ferroelectric design. From the perspective of chemistry, chirality can also be achieved through other methods, namely, the construction of axial chirality and planar chirality. WebIn the polar chiral phase, 4PBA−CdCl 4 gives a significant CD signal and has a moderate ferroelectric polarization of 0.35 μC/cm 2. In addition, 4PBA−CdCl 4 occupies a wide band gap of 4.376 eV that is chiefly contributed by the inorganic CdCl 6 octahedron. This finding offers an alternative pathway for designing new phase transitions and ...
