Elastic organic crystals with ultralong phosphorescence for flexible anti-counterfeiting

Abstract Ultralong organic phosphorescence (UOP) crystals have attracted increased attention due to the distinct photophysical property of a long-lived lifetime. However, organic crystals are generally brittle, leading to a serious problem for their application in flexible technology. Herein, we rep...
