| Abstract: | A new cationic iridium complex has been developed with 2-(1-phenyl-1H-pyrazol-3-yl)pyridine as the ancillary ligand, which bears a pendant protective phenyl ring within the molecule; blue-green light-emitting electrochemical cells (LECs) based on the complex show dramatically enhanced stability compared to the LEC based on a similar complex without pendant phenyl rings. |
