英文摘要： High efficiency, long lifetime and low cost is the driving force for full-scale commerciallization of OLED in large area displays and solid state lighting from the view of materials, making it as the significant research aspects. This project is based on study and development of cost-effective OLED materials, with the aim of preparing high efficiency and long-lifetime single and white light OLED devices. By directly using commercially cheap starting materials, several series of various p-n stuctrured organic electroluminescent host materials and the 3rd gernaration OLED emitting materials are designed and synthesized in a one step reaction. By solving the key issue of the internal relationship between the molecular strucutre of materials and their electronic energy levels, thermal, solid state properties and opto-electronic performance,this project places the emphasis on the blue fluorescent emitting materials which can be simultaneously used as highly efficient organic phosphorescent and/or fluorescent host and novel thermally delayed fluorescent materials,as well as other colored TADF materials, and thus to realize the communal emission of host and guest. Then simple stucture, less materials contained and high efficiency white OLED can be obtained. It is expected to develop a few kinds of cheap but high performance OLED materials with perspective application and our own intellectual property right. Consequently, break the block of excellent OLED materials and device performance from oversea countries to China, and finally promote the development of OLED display and lighting technology.
