An organic electroluminescent device includes a substrate, a first electrode arranged on the substrate, and a functional organic layer arranged on the first electrode. The functional organic layer is adapted to emit electromagnetic radiation A second electrode is arranged on the functional organic layer. The functional organic layer includes a matrix material and an emitter material. The emitter material is neutral or ionically charged. The emitter material is selected from the group of ionic transition metal complex, neutral transition metal complex, polymer emitter and combinations thereof, wherein the matrix material comprises at least one ionic charge carrier transporting material, wherein the ionic charge carrier transporting material is selected from the group of electron-transporting material, hole-transporting material, ambipolar-transporting material and combinations thereof, and wherein the at least one ionic charge carrier transporting material is ionically charged.
2-Phenylpyrimidine skeleton-based electron-transport materials for extremely efficient green organic light-emitting devices
2-Phenylpyrimidine skeleton-based multifunctional electron-transport materials are designed and synthesized. By using these materials and green phosphorescent emitter, fac-tris(2-phenylpyridine)iridium [Ir(ppy)3], extremely efficient green organic light-emitting devices are developed. The devices show the efficiencies of 128 lm W−1 (105 cd A−1) at 100 cd m−2 and 96 lm W−1 (99 cd A−1) at 1000 cd m−2.
设计并合成了基于 2-苯基嘧啶骨架的多功能电子传输材料。利用这些材料和绿色磷光发光体--面-三(2-苯基吡啶)铱[Ir(ppy)3],开发出了极其高效的绿色有机发光器件。这些器件在 100 cd m-2 和 1000 cd m-2 条件下的效率分别为 128 lm W-1 (105 cd A-1)和 96 lm W-1 (99 cd A-1)。
