Highly Phosphorescent Iridium Metal Complexes for Energy-Efficient OLED Applications

A highly efficient iridium metal complex based on 2-phenylpyridine and acetylacetone is prepared via a chemical route. The structural conformation of the complex was achieved using NMR and elementary analysis CHNS. The complex was further analyzed through various photophysical and electrochemical techniques. The energy transfer mechanism has been studied between our guest molecule and a well-known host molecule Poly (n-vinyl carbazole) (PVK). Furthermore, a preliminary OLED device has been prepared to investigate the role of the complex in phosphorescent light-emitting devices.
