Outline of Final Research Achievements

The synthesis of organophosphine-organic/inorganic-polymer hybrid polymers with various structures has been established using P-C cross-coupling polymerization. Water-soluble polymer catalysts and novel materials with self-healing properties were developed by the application of the synthesized hybrid polymers, especially on complexation with transition metals. The P=S-polymer-Pd sub-nanoparticle catalysts have been shown to exhibit unique selectivity. In addition, many valuable findings on organophosphine chemistry were obtained, including the synthesis of chiral phosphines and cyclic phosphine compounds.
