Orange to red iridium( iii ) complexes possessing good electron mobility with a pyrimidine-4-carboxylic acid ligand for high-performance solution-processed OLEDs with an EQE over 31%

Three novel iridium(III) complexes with pyrimidine carboxylic acid as the auxiliary ligand were designed, showing adjustable emission peak wavelengths from 559 nm to 610 nm with relatively high photoluminescence quantum...
