Research & Development
We create a variety of functional molecules synthesized by iron-catalysis.
What is OLED?
Organic Light Emitting Diode (OLED) is a light-emitting diode that uses the electroluminescence phenomenon to emit visible light in response to light-emitting element current.
It has a structure in which both sides of an OLED film, the size of which is several hundred nano meter, are sandwiched between electrodes. The electrons and holes injected into the OLED film from the electrodes move within the OLED film and recombine in the light-emitting layer, causing the organic molecules in the light-emitting layer to emit light.
Advantages of OLED Display
OLEDs are mainly used as a material for digital displays and offer the following advantages over conventional LCD-based displays.
Our OLED
We synthesize various OLED materials to synthesize new materials using iron catalysts developed in the Nakamura Group of ICR Kyoto University.
Furthermore, our strong network with domestic and overseas companies enables us to provide flexible and fine services to our customers.
Research Achievements of Nakamura Group, ICR Kyoto Univeristy
The Nakamura group at the Institute for Chemical Research, Kyoto University, has been studying iron-catalyzed molecular transformations.
Their unique phosphorus ligand, SciOPP, has shown excellent accomplishments in iron-catalyzed cross-coupling reactions, and the results were awarded the 2017 Chemical Society of Japan Award for Academic Achievement. Also, our research on iron-catalyzed reactions has been highly acclaimed internationally, with more than 2,000 citations of relevant papers.

Iron-catalyzed reactions can contribute to cost reduction in synthesis because iron is a resource-rich element. As an example, in the amination reaction of aromatic halides, the cost of catalyst can be reduced to at least 1/16 compared with that of a palladium catalyst.
In 2020, we evaluated the performance of blue OLED devices using our new materials. As a result, we have confirmed that blue light emission occurs and it is possible to drive the device at a lower voltage compared to conventional materials.
