文摘
- •
Iridium complexes (1a–2b) were synthesized using pyrazole based ancillary ligands.
- •
DFT and TDDFT calculations were performed for all complexes.
- •
Light-emitting electrochemical cells (LECs) were fabricated and characterized.
- •
LECs based on these complexes resulted in yellow and green electroluminescence.
