Carbazole/α-carboline hybrid bipolar compounds as electron acceptors in exciplex or non-exciplex mixed cohosts and exciplex-TADF emitters for high-efficiency OLEDs

Abstract

Electron acceptors based on the electron-deficient carboline of CbPyCN exhibited better electroluminescence performance than CzPyCN in exciplex or non-exciplex mixed cohosts and exciplex-emitters.
