Ferroelectrics are a kind of functional materials with special properties and value. Among the recently reported ferroelectrics, the ferroelectrics constructed by organic heterocycles have excellent performance and have great application prospects. This paper reviews the nitrogen-containing organic heterocyclic ferroelectrics, which are more common and have outstanding properties, such as 1,4-diazabicyclo[2.2.2]-octane (dabco), quinuclidine. The principle of ferroelectric phase transition and related performance parameters are introduced, and the method of directional design of ferroelectrics is summarized. The aim is to provide reference for the synthesis of ferroelectric materials.
