Abstract

(Figure Presented) Getting the green light: Highly efficient organic light-emitting diodes (OLEDs) have been synthesized from robust green-electrophosphorescent Ir^III complexes based on carbazole derivatives (see picture, HT = hole transporting, EL = electroluminescence). The combination of short triplet lifetime, high emission efficiency, and improved charge-transporting properties allows these OLEDs to achieve peak efficiencies of 12% photons per electron and 38 cd A^-1.
