제목 Aggregation Induced Emission-active Molecular Triad for Efficient Solution-processed Non-doped TADF-OLEDs
초록 Recently, many studies on non-doped organic light-emitting diodes (OLEDs) have been actively conducted by incorporating a single light-emitting molecule into an EML. Especially, emissive materials showing thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) characteristics simultaneously, which could efficiently harvest 100% of excitons and suppress high concentration annihilation, become a promising strategy as EMLs for efficient non-doped OLEDs. In this presentation, we synthesized a novel light-emitting molecular triad (BPCP-2CPC) with dual functionality and applied to solution-processed non-doped OLEDs. The BPCP-2CPC triad contains 9-phenyl-9H-carbazole units as a host moiety tethered to a green emitting core (BPCP) through a cyclohexane unit and exhibits TADF and AIE characteristics simultaneously. The BPCP-2CPC-based non-doped TADF-OLED devices showed a high external quantum efficiency (EQE) of 13.4%.
