| Outline of Final Research Achievements |
The present study was conducted with a view to developing highly efficient environmental purification systems that can allow the collection and subsequent degradation of persistent chemicals with novel metal-organic host materials. For this purpose, a promising material was prepared for the dechlorination of a typical persistent chemical, hexachlorobenzene. In addition, the one-pot conversion of a plant-origin biomass, cellulose, into a platform chemical of valuable materials, 5-hydroxymethylfurfural, was investigated. The formation of 5-hydroxymethylfurfural was observed in reaction media made of quaternary ammonium salts having chemical structures similar to those of surfactants used in the above-mentioned material.

| Academic Significance and Societal Importance of the Research Achievements |
ヘキサクロロベンゼンは残留性有機汚染物質に関するストックホルム条約で規制対象物質になっている。水への溶解度は低いが、わずかに水中に残留しているものは潜在的に水循環を通じて環境中に拡散し、食物連鎖を経て問題が顕在化する恐れがあるため、その処理は重要である。また、5-ヒドロキシメチルフルフラールは高エネルギー密度燃料やプラスチックの原料になり得る化合物であり、石油資源の代替物として注目を集めている。草本系バイオマスの資源化処理ではセルロースの解重合反応を経由する合成経路が鍵となるが、セルロースは通常の溶媒には難溶で反応性が低く、この反応の高効率化は重要である。
