Abstract

Abstract : 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.
