Application

Tris[2-(p-tolyl)pyridine]iridium(III), also known as Ir(mppy)3, is a solution-processable small molecule, used as green phosphorescent dopant in highly-efficient light emitting diode (LED) displays, both perovskite and organic LEDs.
Tris[2-(p-tolyl)pyridine]iridium(III) is widely utilized as a phosphorescent emitter in OLED devices, particularly in green or yellow organic light-emitting diodes (OLEDs). It can be used in R&D studies for the development of advanced display technologies, including flat-panel displays and organic electroluminescent (OEL) displays. It is suitable in studies such as solid-state lighting including white OLEDs (WOLEDs) and organic light-emitting transistors (OLETs). It has been studied as a sensitizer in dye-sensitized solar cells (DSSCs), as a component in hybrid perovskite solar cells. It can be used in the research area of chemical sensor applications.
