7. 研究集会の趣旨及び概要：
ポリ酸に代表される金属―酸素クラスターの科学は，「構成元素の多様化」および「対象サイズの巨大化」にともなって急速に複雑化しつつある。しかし，その成果を実用材料へと結び付けるためには，機能性分子である金属―酸素クラスターを，目的とする機能に最適な形で配置・配列させることが不可欠である。そこで，触媒や電子デバイス等としての効率的機能発現を目指して，高分子・グラファイト・MOF などの表面・内部に金属―酸素クラスターを適切に配置・配列させた機能性複合材料を開発に向けて，分子設計・構造解析・物性開拓・機能発現・複合化の専門家が一堂に会し，それぞれの立場から議論を深めることを目的とし，本会議を開催することとした。
12 ヶ国から 73 名（うち，中国 14 名，UK10 名，フランス 5 名，ドイツ 4 名，インド 4 名など海外から 48 名）の参加者を迎え，下記のプログラムに従って招待講演 32 件，一般口頭発表 15 件，ポスター発表 9 件が行われた。海外
招待講演者 29 名の顔触れは，この分野を牽引する第一線の研究者と，新進気鋭の若手研究者がそれぞれ約半数を占めている。海外からは大学院生も多数参加し，ポスター発表にて成果を披露した。4 日間の会議を通じて興味深
い研究発表と非常に活発な議論が行われ，国際共同研究や研究交流の提案がなされるなど，非常に有意義な会議であった。
