Sterically Hindered Tetradentate [Pt(O^N^C^N)] Emitters with Radiative Decay Rates up to 5.3 × 105 s−1 for Phosphorescent Organic Light‐Emitting Diodes with LT95 Lifetime over 9200 h at 1000 cd m−2 (Small 12/2024)

Organic Light-Emitting DiodesIn article number2307393, 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.
