one of the grand challenges, principally because the emissive complexes employed either
do not possess sufficiently high photoluminescence quantum yields or exhibit unsatisfactory
Commission International de l'Éclairage (CIE) coordinates. Here two deep‐blue‐emitting
homoleptic iridium (III) complexes are reported and OLEDs are demonstrated with CIE
coordinates of (0.15, 0.05) and maximum external quantum efficiency of 13.4%, which …
