A new and simple strategy towards electric-fielddriven multiple chirality switching device has been designed and fabricated by combining a newly synthesized baseresponsive chiroptical polymer switch (R-FLMA) and pbenzoquinone (p-BQ) via proton-coupled electron transfer (PCET) mechanism. Clear and stable triple chirality states (silence, positive, negative) of this device in visible band can be regulated reversibly (> 1000 cycles) by adjusting voltage programs. Furthermore, such chiral switching phenomena are also accompanied by apparent changes of color and fluorescence. More importantly, the potential application of this device for a spatial light modulator has also been demonstrated.
