| Outline of Final Research Achievements |
We synthesized a molecular composed of a rotor unit and a metal-binding site,which enabled us to construct a 2D aggregate of the molecular rotor by LB method in a presence of metal ions. The membrane structure of which thickness corresponded to the height of the rotor molecules was observed by using AFM measurements, indicating the formation of the target substance. UV-Vis absorption spectra before and after the reaction with metal ions are almost identical, indicating that the structure of the rotor was sustained. To observe the correlated motion of the molecular rotors, temperature dependent UV-Vis absorption measurements was conducted. However, no evidence of the phase transition induced by the motion of rotor was obtained.

本研究では、２次元分子ローターの集積によって、分子機械のミクロな運動が連動しあうことで、キラル反転を伴ったマクロな相転移へと発展するか検証することを目標とした。これは、単純な運動にとどまっていた分子機械を連結することで、より複雑な運動を実現しようとする試みであり、これが成功すれば分子機械研究に大きなインパクトを与えうる。研究の過程において、金属配位サイトを有する分子ローター錯体を合成し、LB法を組み合わせることで、２次元分子ローター集積体の構築手法を開発・実行することに成功した。
