Precise Molecular Design of TADF Sensitizer With Balanced Exciton Dynamics for High-Performance Narrowband Hyperfluorescence OLEDs.
Hyperfluorescence (HF) organic light-emitting diodes (OLEDs) hold great promise for next-generation displays for the simultaneously high color-purity, high efficiency, and long operational stability. However, the development of purely organic thermally activated delayed fluorescence (TADF) sensitizers remains challengi...
