Abstract
Achieving simultaneous polarization and spin switching at room temperature is essential for advanced multi-state storage and control applications, particularly in magnetoelectrics and electron spintronics, yet such materials are exceedingly rare. Based on polar molecular valence tautomerism of CoIII(3,5-DBcat)(3,5-DBsq)(trans-4-stypy)2 (1), room-temperature spin and polarization switching was achieved via electron transfer. Notably, the ferroelectric polarization and spin switching in 1 are modulated by both temperature and light. The successful implementation of room-temperature polarization and spin switching in 1 signifies an important advancement toward practical applications.
