Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a derivative containing a triazine structure, a preparation method thereof, and an organic electroluminescent device. Background technique [0002] With the progress of the information industry, traditional displays can no longer meet people's requirements, such as: cathode ray tube (CRT) displays have large volume and high driving voltage; liquid crystal displays (liquid crystal display, LCD) have low brightness and narrow viewing angles. , The operating temperature range is small; the plasma display panel (PDP) is expensive, the resolution is not high, and the power consumption is large. [0003] Organic light-emitting diodes (organic light-emitting diodes, OLEDs) as a new display technology has unparalleled advantages in various performances of existing display technologies, such as full solid state, self-luminous, high brightness, high resolution , wi...
