The Organic Light Emission Diodes (OLED) device technology can be used for manufacturing novel display products and novel lighting products, is expected to replace the existing liquid crystal display and fluorescent lamp lighting, and has wide application prospect. The OLED light-emitting device is of a sandwich structure and comprises electrode material film layers and organic functional materials clamped between different electrode film layers, and the various different functional materials are mutually overlapped together according to the application to form the OLED light-emitting device. When voltage is applied to two end electrodes of the OLED light-emitting device as a current device, positive and negative charges in the organic layer functional material film layer are acted through an electric field, and the positive and negative charges are further compounded in the light-emitting layer, namely OLED electroluminescence is generated.
At present, the OLED display technology has been applied in the fields of smart phones, tablet computers, and the like, and will further expand to large-size application fields such as televisions, but compared with actual product application requirements, the light emitting efficiency, the service life, and other performances of the OLED device need to be further improved. The research on the improvement of the performance of the OLED light emitting device includes: the driving voltage of the device is reduced, the luminous efficiency of the device is improved, the service life of the device is prolonged, and the like. In order to realize the continuous improvement of the performance of the OLED device, not only the innovation of the structure and the manufacturing process of the OLED device but also the continuous research and innovation of the OLED photoelectric functional material are needed to create the functional material of the OLED with higher performance.
The photoelectric functional materials of the OLED applied to the OLED device can be divided into two broad categories from the application, i.e., charge injection transport materials and light emitting materials, and further, the charge injection transport materials can be further divided into electron injection transport materials, electron blocking materials, hole injection transport materials and hole blocking materials, and the light emitting materials can be further divided into main light emitting materials and doping materials.
In order to fabricate a high-performance OLED light-emitting device, various organic functional materials are required to have good photoelectric properties, for example, as a charge transport material, good carrier mobility, high glass transition temperature, etc. are required, and as a host material of a light-emitting layer, a material having good bipolar property, appropriate HOMO/LUMO energy level, etc. is required.
The OLED photoelectric functional material film layer for forming the OLED device at least comprises more than two layers of structures, and the OLED device structure applied in industry comprises a hole injection layer, a hole transport layer, an electron blocking layer, a light emitting layer, a hole blocking layer, an electron transport layer, an electron injection layer and other various film layers, namely the photoelectric functional material applied to the OLED device at least comprises a hole injection material, a hole transport material, a light emitting material, an electron transport material and the like, and the material type and the matching form have the characteristics of richness and diversity. In addition, for the collocation of OLED devices with different structures, the used photoelectric functional materials have stronger selectivity, and the performance of the same materials in the devices with different structures can also be completely different.
Therefore, aiming at the industrial application requirements of the current OLED device, different functional film layers of the OLED device and the photoelectric characteristic requirements of the device, a more suitable OLED functional material or material combination with high performance needs to be selected to realize the comprehensive characteristics of high efficiency, long service life and low voltage of the device. In terms of the actual demand of the current OLED display illumination industry, the development of the current OLED material is far from enough, and lags behind the requirements of panel manufacturing enterprises, and the development of organic functional materials with higher performance is very important as a material enterprise.
