Research Summary

“Can we show the general methodology for development of highly active & reusable catalysts?”, “If we can develop ultimately highly active catalysts, can they promote unrealized reactions?”, “If we cover catalysts with light, what reactions will be promoted?”, and “Can we develop suitable catalysts towards green sustainable chemistry?” It is our mission in this new team (established in FY2018) to show our answers against the above-mentioned questions. For this purpose, we will develop self-organized catalysts of polymer ligands and metal species, spatial catalysts where micro/nano space materials and catalytic molecules/clusters are merged, and photo-exited catalysts, on the basis of inspiration from enzymes, as well as living orgasms and materials that conduct photoelectric conversion.
