Development of Solid State Molecular Motors

将有机铵/[18]冠-6衍生物组成的超分子阳离子引入到具有磁性的阴离子物种如[Ni（dmit）2]的晶体中。通过NMR测量、理论计算等方法研究了分子的旋转。其中，（m-fluoroanillinium）（dibenzo[18]crown-6）[Ni（dmit）2]晶体显示出基于芳基的翻转运动的铁电性质。并探讨了应用于多铁性化合物的可能性。

Supramolecular cations composed of organic ammonium/[18]crown-6 derivatives were introduced in crystals of anionic species such as [Ni(dmit)2] which showed magnetic properties. Molecular rotations were examined by NMR measurements, theoretical calculation, etc. Among others, (m-fluoroanillinium)(dibenzo[18]crown-6)[Ni(dmit)2] crystal showed ferroelectric properties based on flip-flop motion of aryl groups. Possibility of application to multiferroic compounds was also studied.
