Outline of Final Research Achievements

Polynuclear complexes from [PtL2]5 to [PtL2]12 were formed and could be isolated by size exclusion chromatography (SEC). We prepared ultrafine platinum clusters (Pt5-Pt12) whose number of constituent atoms is corresponding to the atomicity of the precursors. Thiol deprotection from the platinum thiolate [PtL2]x successfully provided the cluster catalyst.

Academic Significance and Societal Importance of the Research Achievements

金属クラスターは次世代の触媒として大いに期待されている。一般的に気相合成法では質量分割をともなうため、得られる単分散クラスターの量は数ng程度が上限であり、実用には不向きであった。本手法では、バッチ式の化学合成法であるため、mgからgオーダーのスケールが可能であり、精度と合成スケールを併せ持った新しい方法であり、本分野の進展に大きく貢献する。
