Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 435294-03-4, is researched, Molecular C35H27N2O2Ir, about Lead-Halide Perovskite as the Host Material for Solution-Processed Phosphorescent Organic Light-Emitting Diodes, the main research direction is Lead Halide perovskite host material Solution Processed phosphorescent organic.SDS of cas: 435294-03-4.
Phosphorescent organic light-emitting diodes (PhOLEDs) are a kind of highly efficient and solution-processable devices for displays and light sources, which employ phosphorescent material as the guest and the carrier transport material as the host in the emission layer (EML). Organic-inorganic perovskites, which possess unique bipolar carrier transport ability and can be facilely fabricated from solution precursors, are potential candidates for host materials of solution-processed PhOLEDs. Herein, we report the use of lead-halide perovskite, MAPbBr3 (MA = CH3NH3), as the host material of a phosphorescent emitter, bis(1-phenyl-isoquinoline-C2,N)(acetylacetonato)iridium(III) (Ir(piq)2acac). The MAPbBr3:Ir(piq)2acac EML was fabricated through solution-processing, and the corresponding PhOLEDs exhibit bright pure red electroluminescence (EL) originating from Ir(piq)2acac in the MAPbBr3:Ir(piq)2acac EML. Using steady and dynamic luminescence techniques, we prove that MAPbBr3 perovskite acts as the host material in the EML and that the charge transfer plays a critical role in the EL process of Ir(piq)2acac. This work proves the potential of the lead-halide perovskites utilized as the host materials in PhOLEDs.
