Description

technical field [0001] The invention relates to a light-emitting material and a light-emitting component, in particular to a quinoxaline-fused cis-stilbene / fluorene spirochete derivative material and an organic light-emitting diode component. Background technique [0002] With the advancement of electronic technology, light-weight and high-efficiency flat-panel display devices are also booming. Organic electroluminescent devices are expected to become the mainstream of next-generation flat-panel display devices due to their advantages such as self-luminescence, no viewing angle limitation, power saving, easy process, low cost, high response speed, and full-color display. [0003] Generally, an organic electroluminescence device includes an anode, an organic light emitting layer and a cathode. When a direct current is applied to the organic electroluminescence device, holes and electrons are injected into the organic light-emitting layer from the anode and the cathode respec...
