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.
