Outline of Final Research Achievements |
The purpose of this research project is to develop a new science that links the functions of porosity and framework by exploring the electronic properties of the framework, which has not been explored in the field of porous coordination polymers (PCPs). The formation of isostructural PCP family from redox-active metal clusters and redox-active ligands was successfully demonstrated, where the structure and function were systematically tuned by ligand exchange. In addition, the chemistry of two-dimensional sheet PCPs, which were previously composed of only one ligand and a metal ion, was extended to obtain two-dimensional sheet PCPs composed of two different ligands. The dual-ligand based PCP nanosheets provided a new design for the modulation of electronic conductivity and porosity. Based on these materials, we will develop further functions and applications in the future.

Academic Significance and Societal Importance of the Research Achievements |
高い電気伝導性を有する多孔材料は、バッテリーやスーパーキャパシタ、燃料電池、電気化学触媒など様々な応用に非常に重要である。そうした材料として、ポーラスカーボンやメソポーラス孔を有する金属酸化物が挙げられるが、これらはアモルファスであるか長周期構造を持たないものである。高い電気伝導性と規則的なナノ細孔の両方を同時に有する多孔材料は研究開始当初において報告例がほとんど無かった。本研究で開発された伝導特性と多孔性を両立する多孔材料は、電気触媒やセンサーを含む様々な応用の基盤となりうることからも、その学術的・社会的な意義を有している。
