研究目的
Investigating the aggregation-induced phosphorescence enhancement in deep-red and near-infrared emissive iridium(III) complexes for solution-processable OLEDs.
研究成果
The study successfully demonstrated the AIPE effect in deep-red and NIR emissive iridium(III) complexes, with Ir2 showing significant enhancement in emission efficiency. The fabricated PhOLEDs exhibited high EQE, indicating the potential of these complexes in solution-processable OLED applications.
研究不足
The study faced limitations such as the low solubility of Ir3 hindering its measurement in aggregation studies and the reduced EQE of Ir4 devices due to the bandgap law.
