Efficient pure blue hyperfluorescence devices utilizing quadrupolar donor-acceptor-donor type of thermally activated delayed fluorescence sensitizers
Abstract
A suppressed energy loss through Dexter energy transfer is crucial to achieve highly efficient blue organic light-emitting diodes. Here, authors synthesize quadrupolar donor-acceptor-donor type thermally activated delayed fluorescence sensitizers and realize device with maximum efficiency of 43.9%.
