Outline of Final Research Achievements	In this paper, some coordination polymer with nanocrystal morphology control effect have been found by the screening test of the many coordnation polymer of silver. The polydispersed silver nanoplate with various selectively synthesized by the reduction of coordination polymers using PVP solution. Nearly monodisperse silver nanoplate was synthesized by tuning reduction-oxidation and deposition-dissolution reaction ratio of silver oxalate.
Free Research Field	ナノ材料合成
Academic Significance and Societal Importance of the Research Achievements	運動が制限された固体である配位高分子が異方性結晶を選択的に析出する反応場としての効果の証明により、擬似的な固相反応により平板形状を有する異方性ナノ結晶合成法の可能性が広がる。さらに、形状・サイズ単分散性も液相合成同等のレベルまで向上させることができた。これにより、液相合成の最大の課題であった廃液を100分の1程度まで減少させることができる。
