A light emitting device is characterised in that it is a device having a structure in which at least an anode, an emissive layer, an electron transporting layer and a cathode are provided as layers in turn, and which emits light by means of electrical energy, and said device has a benzoquinoline derivative. The benzoquinoline derivative may have a plurality of benzoquinone skeletal structures, including a plurality of benzoquinone skeletal structures connected by conjugated bonds, an aromatic hydrocarbon, an aromatic heterocycle or mixture thereof.
Example light emitting devices have a structure in which at least an anode, an emissive layer, an electron transporting layer and a cathode are provided as layers in turn and which emits light by means of electrical energy, and the organic compound is an organic compound of molecular weight at least 400, glass transition temperature at least 90°C, ionization potential at least 5.9 eV and having a benzoquinoline skeletal structure.
一种发光器件,其特征在于它是一种具有至少阳极、发射层、电子传输层和阴极依次作为层的结构,并通过电能发光的器件,所述器件具有苯并喹啉衍生物。苯并喹啉衍生物可具有多个苯醌骨架结构,包括通过共轭键连接的多个苯醌骨架结构、芳香烃、芳香杂环或它们的混合物。
示例发光器件具有至少阳极、发射层、电子传输层和阴极作为层依次设置的结构,该结构通过电能发光,而有机化合物是分子量至少为 400、玻璃化温度至少为 90°C、电离电位至少为 5.9 eV 且具有苯并喹啉骨架结构的有机化合物。
