Highly efficient white organic light-emitting diodes based on balanced bipolar-transporting blue hybridized local charge transfer fluorophores

Abstract

Fluorescent/phosphorescent hybrid white organic light-emitting diodes (WOLEDs) combining the blue fluorophore with long-wavelength emissive phosphors have attracted a great deal of attention in the fields of solid-state lighting and full-color...

Deep-red/NIR AIEgens based on electron-withdrawing dithiafulvalene-fused benzothiadiazole for solution-processed non-doped OLEDs

“…[29][30][31][32][33][34][35] By employing the design principles of hybridized local and charge transfer (HLCT) and thermally activated delayed fluorescence (TADF), the limit of 25% EQE in OLED devices could be broken. [36][37][38][39] However, the design of efficient HLCT and TADF characterized DR/NIR molecules is still challenging, especially those with high PLQY. Moreover, most DR/NIR luminogens having a D-A structure easily suffer the aggregation-caused quenching (ACQ) effect due to the strong intermolecular p-p stacking resulting from the intermolecular D-A interactions.…”
