Highly efficient phosphorescent materials based on platinum complexes and their application in organic light-emitting devices (OLEDs)

Although numerous materials can be utilised as emitters in electroluminescent devices, platinum complexes bearing organic ligands are among the most promising for use as highly effi cient phosphorescent materials in which the singlet and triplet states can be simultaneously harvested for emission. This article aims to give an overview of recent progress in Pt phosphors featuring ingeniously designed ligands and to summarise their impressive performances when incorporated into organic light-emitting devices (OLEDs). Such materials show great promise for applications such as fl at screen displays and low-energy solid-state lighting.
