Exciplex-thermally activated delayed fluorescence (exciplex-TADF) system is an excellent candidate for fabrication of high-efficiency organic light-emitting diodes (OLEDs) because of its more easily achieved small singlet–triplet energy splitting (Δ E ST ) and doping-control. However,...

Efficient deep-blue emitters with nice color purity are fundamental in organic light-emitting diode (OLED) applications. Herein, we report two phenanthroimidazole (PPI) derivative deep-blue emitters ( DP , SP ) with hybrid local and charge-transfer (HLCT) properties of high photoluminescence...

Progress in coopetition research is impeded by three problems in the literature: (a) conceptual ambiguity surrounding the coopetition construct; (b) insufficient understanding of contingency factors; and (c) a lack of consideration of potential variations in coopetition structures. Especially in...
