Discovery of amantadine formate: toward achieving ultrahigh pyroelectric performances in organics
Pyroelectrics are a class of polar compounds that output electrical signals upon changes in temperature. With the rapid development of flexible electronics, organic pyroelectrics are highly desired. However, most organics suffer from low pyroelectric coefficients or low working temperatures. To date, the realization of superior pyroelectric performance in all-organics has remained a challenge. Here, we report the discovery of amantadine formate, an all-organic pyroelectric with ultrahigh voltage figures of merit (Fv), surpassing those of all other known organics and commercial triglycine sulfate, LiTaO3 as well around room temperature.
