Description
Technical Field
The invention relates to the technical field of organic electroluminescent materials, in particular to a triarylamine derivative and an organic electroluminescent device thereof.
Background
In recent years, organic semiconductor materials are one of the most active directions in the material field, and compared with inorganic semiconductor materials, the organic semiconductor materials have the advantages of good solubility, high transparency, easy processing, fast photoelectric response, potential biocompatibility and the like, and are increasingly important in the application in the high and new technical fields of photoelectric conversion, photovoltaic cells and the like. The OLEDs (Organic Light Emitting Diode) organic electroluminescent device has the remarkable characteristics of simple structure, high response speed, active luminescence, light weight, thinness, luminescent color diversity, wide viewing angle, low energy consumption and the like, has obvious advantages in the fields of display and illumination, and is widely focused on technical application, scientific research and the like.
With the development of materials of various functional layers of OLEDs, materials with various properties are continuously emerging, and in order to adapt to the diversity of materials, the structure of the devices is continuously optimized. According to the number of organic functional layers, the device structure is simply divided into a single-layer device, a double-layer device, a three-layer device and a multi-layer device, most of the current OLEDs devices mostly adopt a multi-layer sandwich type double-carrier direct current injection type device, and the device is generally composed of an anode Indium Tin Oxide (ITO) with a high work function, a metal cathode with a low work function and an organic functional layer, wherein the organic functional layer mainly comprises a Hole Transport Layer (HTL), an emitting layer (EML) and an Electron Transport Layer (ETL). Under the action of an externally applied electric field, electrons and holes generated by the cathode and the anode are injected into the middle organic film layer, the injected electrons and holes migrate to the light-emitting layer in the electron transmission layer and the hole transmission layer, remain in the light-emitting layer to the greatest extent, increase the recombination opportunity, form excitons, the excitons transition back to the ground state in a radiation mode, and a light-emitting phenomenon is generated, namely, electroluminescence is generated, and the energy level from the excited state to the ground state determines the light-emitting color.
The hole transport layer which is one of the most important functional layers in the OLEDs has the basic functions of improving the transport efficiency of holes in the device, effectively blocking electrons in the light-emitting layer and realizing the maximum recombination of carriers; meanwhile, the energy barrier of holes in the injection process is reduced, and the injection efficiency of the holes is improved, so that the brightness, the efficiency and the service life of the device are improved. Therefore, the excellent hole transport material should have good film forming property, good thermal stability, and appropriate HOMO orbital energy level to ensure efficient injection and transport of holes between the electrode and the organic functional layer, and should also have high hole mobility. Therefore, it is an urgent need to develop a hole transport material having a suitable HOMO orbital energy level and a high hole mobility, and to improve the thermal stability and film forming property of the material by adjusting the structure of the material.
