Abstract

Let your light shine: By using pincer-type cyclometalated PtII arylacetylide complexes as dopants, a maximum current efficiency of 26.57 cd A−1 (22.12 cd A−1 at 1000 cd m−2) has been achieved with solution-processable phosphorescent OLEDs, the highest ever reported for this type of devices based on phosphorescent PtII emitters.
