Preparation and electroluminescent characteristics of a series of cyclometalated Ir(III) complexes based on phenylpyridines with a diphenylamino group
A series of cyclometalated iridium complexes with a strong electron-donating and bulky diphenylamino group was prepared and the phosphorescence wavelengths were found to be greatly dependent on the substituent positions: some of them afforded high performance electroluminescence (EL) devices.
