Outline of Final Research Achievements

Graphene nanoribbons (GNRs), defined as nanometer-wide stripes of graphene, have attracted significant attention as candidates for next-generation semiconductor materials. The structural perfection of GNRs is an essential issue because their physical properties are critically dependent on nanoribbon’s width and edge geometry. Metal&-organic frameworks (MOFs), porous materials formed through the self-assembly of metal ions and organic ligands, have been applied to a variety of applications, including gas storage, separation, and catalysis. MOFs have the advantages of the tunable and regulated nature of their nanospaces and have been shown to provide an ideal compartment for controlling the arrangement of guest species through the geometrical constraint of host pores, as well as non-covalent interactions between host and guest. Here, we disclosed a new method for the synthesis of GNRs utilizing the MOFs as a template.

Academic Significance and Societal Importance of the Research Achievements

本研究では高分子材料化学、ナノカーボン化学、構造有機化学、錯体化学を横断した学際的な分野に挑戦し、従来法では合成が困難であった新規ナノカーボン物質を作り出すことに成功した。鋳型となるMOFは簡便に作製することができるため、本手法によって、構造が精密に制御されたGNRのバルクスケール合成が初めて可能になった。そのため、GNRの様々な分野へのサンプル提供が可能になり、光電子デバイスの機能向上など、材料化学に大きく貢献することが期待される。
