Notice of Signing of Joint Development Agreement with Nippon Soda Co., Ltd., Regarding New Next-Generation OLED Compound

Fukuoka, Japan, October 14, 2020- Kyulux Inc. (Headquarters: Fukuoka, President: Junji Adachi) is pleased to announce the signing of a joint development agreement with Nippon Soda Co., Ltd., (Headquarters: Chiyoda-ku, Tokyo, President: Akira Ishii) regarding a new compound for TADF, a next-generation OLED emitter material technology. 

Nippon Soda celebrated its 100th anniversary in February this year, and aims to develop new products and expand into new businesses with its long-term management vision, “Brilliance through Chemistry 2030”, and three-year medium-term business plan, “Brilliance through Chemistry Stage I”. Nippon Soda utilizes its advanced organic material development capabilities and vast synthesis know-how, cultivated over many years. Nippon Soda will work on the joint development of the intermediates with the aim of improving the performance and quality of TADF materials that rare metal free developed by Kyulux. It will also aim to and dramatically improve the production efficiency of new compounds.

Kyulux is a fabless startup company developing TADF/Hyperfluorescence™ materials, the next-generation of OLED materials. The OLED display market continues to grow rapidly as an alternative to the LCD market, and in the future, with the introduction of 5G communication technology, further lower power consumption and higher performance will be required. TADF materials embody a new approach that reduces the environmental impact without using any rare metals, and Kyulux’s Hyperfluorescence™ platform uses this TADF to achieve high efficiency, high resolution, high color purity, low energy demands and low cost at the same time.

Junji Adachi, President of Kyulux, commented: “We have continued to develop next-generation OLED materials as a startup company, but prior to commercialization, the production of high quality and low cost TADF materials was an important issue. I am truly grateful that Kyulux has established the close and long-term partnership with Nippon Soda, and this joint development is a major event for the OLED display industry, which awaits the early mass production of TADF”

Natsuki Amanokura, Ph.D., Business Development Department, Chemicals Business Division at Nippon Soda, commented: “Being able to start joint development of new intermediates for TADF with Kyulux is exactly the deliverables of the open innovation efforts that we were aiming for. We can build a wonderful Win- Win relationship by combining the knowledge of Nippon Soda and Kyulux. I am very much looking forward to the future business development”

[About TADF – Thermally activated delayed fluorescence]

The emissive layer of an OLED display is its most important layer, where the electric charge is combined with the organic materials and light is emitted. The emissive layer is composed of an emitter and a host, and is the subject of intensive research and development efforts.

TADF emitters set out to solve three main challenges with current generation OLED emitters:

  • Low cost and non-heavy-metal alternative to current red and green phosphorescent emitters
  • Efficient and long-lasting soluble emitters suitable for ink-jet printing
  • An efficient and long-lasting blue emitter

TADF was pioneered by Kyushu University’s Prof. Adachi and his world-renowned Organic Photonics and Electronics Research center (OPERA). TADF research began in 2009, and in recent years there is an extensive R&D effort by academics and enterprises all over the world.

[About Hyperfluorescence™]

Kyulux’s Hyperfluorescence™ is a technology that combines TADF with a fluorescent material to transfer energy from TADF to fluorescent molecules to emit light. It is extremely efficient and has a long device life without the use of rare metals, achieved high color purity light emission.
