[(Histamine)(18-crown-6)2][BF4]2 is a high-temperature piezoelectric†
Abstract
We discovered that [(histamine)(18-crown-6)2][BF4]2 is a high-temperature host–guest inclusion complex that presents decent piezoelectric properties (d33 = 5 pC/N), undergoes a phase transition at 406 K, and also possesses potential ferroelectricity. This work provides a new idea for constructing host–guest inclusion piezoelectrics.
