| Outline of Final Research Achievements |
Asymmetrical z-bar linkage precursor was organically synthesized aiming at ferromagnetic graphene nanoribbons. We tried to fabricate GNRs using our developed two-zone chemical vapor deposition method. Although expected GNRs were not produced, two-dimensional organized structures were observed. Annealing process over 400 degrees is the reason to produce such structures due to intermolecular coupling of GNRs via decomposition of functional groups. These results will provide a useful knowledge to fulfill out goal.

| Academic Significance and Societal Importance of the Research Achievements |
従来の対称型ジグザグエッジGNRで予測される鎖内エッジ間でのスピンの相殺の問題を克服するため、片側エッジのみにジグザグ構造を持つ新しい非対称型GNR構造を提案した。この構造を実現するために、非対称Z型前駆体分子を設計し、我々が世界に先駆けて見出した“生物模倣触媒作用” （H. Sakaguchi, et al., Nat. Chem., 9, 57 2017）を利用した、強磁性を有する非対称型ジグザグエッジGNRの提案を行った。
