19_02b/2007Inside Front Cover: Excimer-Based White Phosphorescent Organic Light-Emitting Diodes with Nearly 100 % Internal Quantum Efficiency (Adv. Mater. 2/2007)

By combining the monomer and excimer/aggregate emission of FPt, a white OLED can be obtained. Incorporating the novel host material 26mCPy and engineering the charge balance properties, Jabbour and co-workers used FPt to demonstrate, for the first time, nearly 100% internal quantum efficiency in white OLEDs (as shown in the image). The work is reported on p. 197.
