Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

FlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Highly efficient blue crystalline organic light‐emitting diodes enabled by a hot exciton sensitizer PyPO

FlexMat, EarlyView.
Two different sensitization structures (hot exciton sensitizer type and exciton nanoaggregate type) were integrated into crystalline host matrix. The resulting crystalline organic light‐emitting diodes exhibit low Joule heat loss ratio and high photon output.
