In article number 2307393, Gang Cheng, Lei Dai, Chi‐Ming Che, and co‐workers realized operationally stable and high‐performance vapor‐deposited green phosphorescent organic light‐emitting diodes with sterically hindered tetradentate [Pt(O^N^C^N)] emitters. The corresponding Pt‐based devices display EL spectra with full width at half maximum down to 36 nm, high external quantum efficiency and CE of up to 27.6% and 98.7 cd A−1, respectively, alongside practical device lifetimes (LT95) of up to 9270 hours at an initial luminance of 1000 cd m−2. |
