摘　　要：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 Co^(Ⅲ)(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.
