Outline of Final Research Achievements

We developed a simple and scalable method to fabricate metal containing magnetic carbon sheets by using planner metal complexes and aromatic compounds as the building blocks and transition metals as the coupling agent. 1. Fused-ring poly-phthalocyanine sheet was successfully prepared by poly-cyclotetramerization reaction using octacyanophthalocyanine building block and an magnetic interaction within 2D sheet was observed. 2. By using chlorinated phthalocyanine as the building block, a porous poly-phthalocyanine has been successfully prepared. Lithium ion adsorption ability of the porous poly-phthalocyanine was tested as anodes in lithium-ion cells and the poly-phthalocyanine exhibited a reversible lithium storage capacity and a cycling performance. 3. By using planner aromatic compounds as the building block, porous 2D carbon nitride was prepared. The porous 2D carbon nitride adsorbed nitrate and metal ions simultaneously and exhibits paramagnetism.

Academic Significance and Societal Importance of the Research Achievements

２次元構造を有する磁性炭素材料は電子スピンの制御も可能とする次世代エレクトロニクス材料のみならず、触媒、電池等、広い分野で有用な材料である。しかしながらその簡便かつ大量生成可能な合成方法は確立されていない。本研究では磁性炭素シートの合成法に関する問題解決を目指している。また、材料の主成分を炭素とすることで、現在対策が求められている希少資源の確保や廃棄の際の環境負荷の問題に対応しており、社会の要請に沿っている。
