The production of semiconductors, OLED displays, all-solid-state batteries, agrochemicals, pharmaceuticals, and fuel cells assumes the use of rare metals such as palladium as catalysts. However, rare metals are toxic and expensive due to limited supply. Iron, on the other hand, is an abundant inexpensive metal with low toxicity which makes it suitable for multiple applications including the manufacturing of electronics and medical products.
Technical Summary
The inventors synthesize a variety of functional molecules using iron-based catalysis.They developed novel iron-bisphosphine complexes with a phosphorus ligand, SciOPP,which have shown excellent performance in C-C cross-coupling reactions (Fig. 1, Adaket al. 2021).
As a proof of concept, the inventors evaluated the performance of blue OLED devices using their new materials. They showed that the device could be driven at a lower voltage compared to conventional materials (Fig. 2). By implimenting iron-catalyzed
reactions, it is possible to reduce the catalyst cost to at least 1/16 compared topalladium. The overall cost of display production can be reduced to 1/3.
TSKis a company that develops materials based on iron-catalyzed synthesis in collaboration with Kyoto University.

Kyoto University was founded in 1897, the second university to be established in Japan. Kyoto University is among 10 National Designated Universities in Japan. It boasts 18 graduate schools, 10 faculties, 12 research institutes, and 26 centers and other establishments. Research conducted at Kyoto University spans the full spectrum of fields from social to natural science.
The outstanding research conducted at Kyoto University gives birth to useful technologies that could greatly benefit society. SACI (Society-Academia Collaboration for Innovation Office) was established at Kyoto University to bridge the gap between researchers and industry. We facilitate joint research, technology transfer, creation of university startups, and provide entrepreneurial education. We are building a strong network of global industry partners to make sure basic research reaches the market.
