Study on organic electroluminescent materials

With the continuous development of science and technology, material science research is gradually advancing, especially the related research content of organic electroluminescent materials, which can not only improve the application efficiency, but also create a more harmonious and efficient scientific research platform. In this paper, the research background of organic electroluminescent materials is analyzed, and the research status of related materials is introduced emphatically.

In recent years, luminescent metal complexes have attracted extensive attention. In order to improve the application value of organometallic luminescent metal complexes in organic light-emitting devices, it is necessary to improve the corresponding work in combination with the specific research process and create a more diversified material analysis mode while comprehensively analyzing the material science content.

With the comprehensive improvement of people’s living standards, people’s material requirements are also increasing. Visual enjoyment is not limited to the original application mode, but to construct a more harmonious transmission information processing mechanism, give full play to the value of organic electroluminescent materials, so as to match corresponding devices and maintain the overall application efficiency. The earliest research on organic electroluminescent materials began in 1963, when the luminescence phenomenon of organic materials was first proposed. Under the action of 400V voltage, the fluorescence phenomenon of single crystal anthracene would appear. Because of the influence of voltage and efficiency at that time, people only know the performance of luminescent materials. Under the background of comprehensive upgrading of the subsequent technology level, the brightness of the device structure will also be above 1000cd/m2 when the device opening voltage is below 10V. Among them, the research scope of OLED is expanding, and its characteristics such as no backlight, ultra-fast response and wide viewing Angle are gradually showing, which can greatly improve the application efficiency of organic electroluminescent materials. Compared to the traditional LIQUID crystal display technology system, OLED can better meet people’s visual needs, the process is simpler and the manufacturing cost is lower.

In addition, all solid state characteristics of organic electroluminescent materials are also analyzed, which is of great significance to the lighting field. In 2017, relevant researchers took quinoxaline derivatives as research receptors, designed and synthesized a series of luminescent materials with relatively special properties, such as TADF and AIE, which can improve quantum efficiency while reducing efficiency attenuation and better control the overall application effect [1]. In addition, TADF and other materials research progress is not advancing, the mode of new fluorescent materials has been widely concerned.

Organic electroluminescent materials is widely used in information processing, communication system, etc., it can better improve display effect, meet people’s visual requirements, in order to further promote the development of organic electroluminescent materials devices commercialization process, not only to integrate technology, also want to for a better material synthetic performance evaluation.
