| Research Abstract |
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.
