A chemical model capable of predicting the operational stability for organic light‐emitting devices is established, as reported by Dongho Kim, Jun Yeob Lee, Youngmin You, and co‐workers in article number 2003832. This model involves Langevin recombination, followed by electron transfer from a dopant to a host exciton, as the key degradation step. The research disentangles the chemical processes in the degradation and provides a useful foundation for enhancing the operational stability of electroluminescence devices.
