| Outline of Final Research Achievements |
This research is aimed at the construction and functionalities of ionic metal complexes consisting of both cationic and anionic complexes. Hydrogen-bonding interactions are often utilized for the aggregation of preorganized discrete molecules. In this work, the new ligand bearing a biguanide moiety as a hydrogen-bonding donor and a carboxylate group as a hydrogen-bonding acceptor was designed, and the porous hydrogen-bonding network structure was constructed. Structural conversion and chiral selectivity were demonstrated. In addition, the phenyl groups were introduced to the ligand system, which resulted in the flexible structural conversion and the molecular recognition.

| Academic Significance and Societal Importance of the Research Achievements |
これまで、水素結合等の弱い分子間相互作用を利用して超分子構造を構築する方法として、単純な構造をもつ無機アニオンを鋳型とする方法が用いられてきた。本研究では、対イオンとして無機アニオンにとどまらず、金属錯体を用いてイオン性金属多核錯体を合成し、機能性開発を目指した。金属錯体の構造や物性の多様性と、柔軟な分子間相互作用に基づく、新奇な機能性発現の可能性を秘めており、その合成戦略の確立は、超分子化学の発展に大きく寄与するものである。
