Multifunctional molecular ferroelectrics are exciting materials synthesized using molecular chemistry concepts, which may combine a spontaneous electrical polarization, switched upon applying an electric field, with another physical property. A high‐temperature ferroelectric material is presented that is based on a chiral Zn2+/Dy3+ complex exhibiting Dy3+ luminescence, optical activity, and magnetism. We investigate the correlations between the electric polarization and the crystal structure as well as between the low‐temperature magnetic slow relaxation and the optical properties.
An attractive glow: A high‐temperature ferroelectric material based on a chiral Zn2+/Dy3+ complex exhibits Dy3+ luminescence, optical activity, and magnetism. Remarkably, this molecular material remains crystallized in a polar structure. This leads to a ferroelectric behavior, making it one of the highest‐temperature working molecular ferroelectrics.
