Abstract
Abstract— Red‐emitting organic electroluminescent devices have been developed that provide exceptional stability, efficiency, and color chromaticity, and which operate at a lower drive voltage. We have identified several superior host‐dopant systems, which, to the best of our knowledge, provide devices with outstanding performance. These devices show projected operational lifetimes (20 mA/cm2), under an ambient temperature, of >25,000 hours and 2000–8000 hours at elevated temperatures (85 and 70°C).Keywords
