The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in organic materials has proven quite elusive to date. In a groundbreaking study earlier this year, croconic acid has been shown to display ferroelectricity above room temperature. From a chemical viewpoint, this molecule belongs to a series of planar monocyclic compounds whose ferroelectric behaviour remains unexplored. The lightest members of this series include deltic, squaric, croconic, and rhodizonic acid. This chemical series represents an ideal test bed to explore how molecular topology maps onto organic ferroelectric, antiferroelectric, and paraelectric behaviour in the solid state. In this proposal, OSIRIS will be used to survey the proton dynamics in this novel class of materials for the first time.
