（化学方程式）和红色一样好：制备了基于铱电致磷光体的高效纯红色OLED，该磷光体用空穴传输三苯胺树枝化基元官能化（见图）。这些双功能树枝状聚合物给出了11.7%的峰值效率，具有优异的颜色质量，并提供了一个有吸引力的途径，为开发金属磷光体与纯红色发光器件所需的优化效率/色纯度的权衡。OLED=有机发光二极管。KGaA
(Chemical Equation Presented) As good as red: Highly efficient pure red OLEDs based on iridium electrophosphors functionalized with hole-transporting triphenylamine dendrons are prepared (see picture). These bifunctional dendrimers give a peak efficiency of 11.7% with an excellent color quality and offer an attractive avenue for the development of metal phosphors with the optimized efficiency/color purity trade-offs required for pure red-emitting devices. OLED= organic light-emitting diode. KGaA.
