N2 - Organic light-emitting diodes (OLEDs) displaying a wide range of emission colors with emission peaks from 450 to 665 nm using a single emitting material, avobenzone boron difluoride (AVB-BF2), are reported. Color tuning is achieved by controlling the aggregation of AVB-BF2 and the formation of a “triadic” exciplex of an AVB-BF2 dimer and a host molecule. Various electroluminescent devices containing AVB-BF2 cover the whole visible light spectrum and a white-emitting device with CIE coordinates of (0.35, 0.37) is obtained with a single emitting material in a single emissive layer. Furthermore, an exceptionally high external quantum efficiency of nearly 13% is achieved for a green-emitting OLED because AVB-BF2 exhibits thermally activated delayed fluorescence by forming the exciplex.
