Abstract:Organic−inorganic hybrid materials (OIHMs) have become a powerful platform for exploring ferroic materials due to the advantages of directional design on the molecular level. Here, based on a hybrid uniaxial ferroelectric (Quinuclidinium)GaCl 4 (QGC), a chiral hybrid (R-3-hydroxylquinuclidinium)GaCl 4 (R3HQGC) was successfully synthesized through a molecular strategy of H/OH substitution. R3HQGC exhibits a much higher Curie temperature (318 K) than QGC (284 K) because hydroxyl modification enhances intermolecu… Show more
