Solid reversible phase transitions of crystalline materials have been widely applied in ferroelectrics, nonlinear optical materials and dielectric switches. Herein, two homochiral crown ether clathrates were synthesized which undergo high‐temperature reversible phase transition. Both compounds display switchable dielectric, heat anomalies and second harmonic generation (SHG) response around 338 K, further confirming the reversible phase transition behavior.
