Provided is an electroluminescent device. The electroluminescent device includes an anode, a cathode, and an organic layer disposed between the anode and the cathode, wherein the organic layer includes a first metal complex of a ligand having a structure represented by Formula 1 and a first compound having a structure represented by Formula 2. The novel material combination comprising the first metal complex and the first compound can be used in an emissive layer in an electroluminescent device. The novel material combination can enable the novel electroluminescent device to obtain a darker red color, a lower voltage, higher efficiency, and a longer lifetime and can provide better device performance. Further provided are an electronic device and a compound combination.
提供了一种电致发光装置。该电致发光装置包括阳极、阴极和位于阳极和阴极之间的有机层,其中有机层包括一个配体的第一金属配合物,该配体具有由公式1表示的结构,以及一个第一化合物,该化合物具有由公式2表示的结构。该新型材料组合包括第一金属配合物和第一化合物,可用于电致发光装置的发射层。该新型材料组合可以使新型电致发光装置获得更深的红色、更低的电压、更高的效率和更长的寿命,从而提供更好的设备性能。此外,还提供了一种电子设备和化合物组合。
