## Abstract Two blue‐emitting cationic iridium complexes with 2‐(1__H__‐pyrazol‐1‐yl)pyridine (pzpy) as the ancillary ligands, namely, [Ir(ppy)~2~(pzpy)]PF~6~ and [Ir(dfppy)~2~(pzpy)]PF~6~ (ppy is 2‐phenylpyridine, dfppy is 2‐(2,4‐difluorophenyl) pyridine, and PF~6~^−^ is hexafluorophosphate), have
## Abstract Here, a new method is presented to increase the turn‐on time and stability of light‐emitting electrochemical cells (LECs). To this end, a neutral iridium complex (**5**) containing a pendant Na^+^ ion that is generally known to have a faster mobility in the solid film than bulky anions
