Outline of Final Research Achievements

We have proposed ketone polymers as a new class of reversible hydrogen careers and elucidated their hydrogen storage property. The fluorenone polymers were synthesized, and electrochemical hydrogenation and catalytic dehydrogenation of the polymers was examined. Especially poly(vinyl fluorenone) was synthesized via radical polymerization, and electrolytically reduced poly(vinyl fluorenone) was hydrogenated in the electrolyte containing water as hydrogen source to be converted to the poly(vinyl fluorenol). The formed poly(vinyl fluorenol) quantitatively evolved hydrogen gas by simply warming with the iridium complex catalyst. The aliphatic ketones were also quantitatively hydrogenated through the bulk electrolysis with the iridium catalyst and applied to the organic hydrogen carrier.
