Chisso cut into the field of OLED light-emitting materials

Chisso released a message that the 2008 year will start selling OLED light-emitting materials. At present, the low molecular blue fluorescent materials have begun to sample shipments. The company in the global market share of liquid crystal material reached 4 or more, for the broad prospects of the next generation of display technology OLED materials, also plans to establish the cause of the foundation. Located in Xiongben production base will invest 3 to 500 million yen, can also be set up the production of light-emitting materials production equipment, a reaction can produce up to a maximum of 10 kg of materials.

OLED forecast will be applied to TV, car end products, mobile phones and other products. Chisso is targeting a large size target. OLED is made up of the "luminous layer" of the electroluminescence and the transport layer of the electron. In 2002, Chisso began to sell the negatively charged electron transport materials. After the light-emitting materials, it also put forward the development of the transport layer of positive charge.

The molecular weight of the low molecular weight material is less than thousands, compared with the polymer type, the purity is high, and the quality is easy to reach a stable level. Fluorescent light emitting material is more than phosphorescent. In the development of OLED related materials, Nippon Steel has completed the development of low molecular phosphorescent luminescent materials in primary colors red, green and blue materials, materials also plans to complete development in the year 2007. In addition, Sumitomo chemical has also invested in the development of polymer materials, plans to enter the 2008 stage of industrialization.
