Design of a heteroleptic green Ir(iii) complex for eco-friendly solution-processed phosphorescent organic light-emitting diodes with external quantum efficiency exceeding 22.

ABSTRACT: The development of eco-friendly solution-processed PHOLEDs (s-PHOLEDs) is a significant issue due to the toxicity of halogenated solvents. However, high-performance s-PHOLEDs have predominantly relied on halogenated solvents, owing to their superior ability to dissolve organic materials and facilitate high-quality film formation in the EMLs. To advance the development of eco-friendly s-PHOLEDs, several criteria are required to solve; the development of emitters and host materials having high solubility in eco-friendly solvents and the establishment of optimal conditions for achieving high-quality films, including uniformity, thickness, and morphology. Herein, we developed eco-friendly s-PHOLEDs using a novel green phosphorescent emitter, MECF-pop, and a new thermally cross-linkable hole tr
