| Outline of Final Research Achievements |
In this research, a metal complex design guideline was established that enables a synthesis concept that is compatible with both solvent-free and precise size tunable synthesis of organic inorganic hybrid nanoparticles to develop and expand the synthesis of nanoparticles of a wider range of metals and metal oxides. advanced. We have realized size control that allows for precise size control of metal complexes that can be freely identified. Development of the relationship between the ligand and decomposition temperature of metal complexes and a nondestructive method for evaluating decomposition temperature, and quantitative evaluation of nanoparticle structure (size/ligand) and nanoparticle dispersion behavior toward the development of artificial three-dimensional super lattices.

| Academic Significance and Societal Importance of the Research Achievements |
液相法によるナノ粒子合成は多量な溶媒・廃液が環境・原料コスト的な問題があり社会実装の大きな障壁となっていた。本研究では、申請者独自技術である融解金属錯体法によ無溶媒単分散ナノ粒子の自在精密サイズ制御合成の汎用性向上を目指し研究を進めた。この成果により、所望の構造・性質を有するナノ粒子を簡便かつ低コストで合成可能とした本成果は、ナノ粒子を原料とした材料合成の開拓、ナノ粒子分散挙動などの基礎物性の評価を可能とする点に学術的意義がある。さらに、低コスト・簡便なナノ粒子合成法はナノ粒子の社会実装をする上で社会的意義もある。
