Organic electroluminescent device (OLED) is a new generation of display technology, whose outstanding characteristics make it the mainstream of international display technology. It has been applied in the latest and most advanced mobile display terminals. It is expected that the market demand will exceed $25 billion in 2017 and $40 billion by 2021. Different from the development mode of "process drive" such as semiconductor chip and LED, OLED technology relies more on "material drive", among which luminous material is the crown of OLED industry and the key to the development of the whole OLED industry.

The project 973 (Basic and Applied Research on Excited States of Metal Complexes), led by Prof. Chi-ming Chi of the University of Hong Kong, developed a tetradentate ligand-based platinum (II) complex, which is likely to replace the commercial phosphoiridium (III) complex, and has attracted great attention from academic and industrial circles at home and abroad. International OLED giant samsung, leading enterprises in guangdong and domestic OLED materials agger legna photoelectric materials company (agger legna) led a group of domestic and international enterprises have applied for a professor about four teeth ligand platinum (II) complexes of related patent licensing, and carried out a series of cooperative research, cumulative amount involved up to tens of millions of yuan, the materials for OLED industry in China are badly in need of knowledge ChanQuanKu. In addition, the project cooperated with Xinli Electronics and other enterprises to carry out the mass production line introduction project of AMOLED; In cooperation with Sichuan Provincial government and Meishan City, Sichuan Zhiben Express Innovation And Technology Research Institute has been jointly established to vigorously develop new OLED luminescent materials and accelerate the industrialization process of materials.

While vigorously developing the metal complex luminescent materials with its own intellectual property, the team is aiming for the next generation of metal complex luminescent materials in the longer term. The highly efficient luminescent gold (III) complex and inexpensive tungsten (VI) complex developed by the project team are likely to be the next generation of the most competitive OLED luminescent materials.
