| Outline of Final Research Achievements |
We have developed a plastic crystal with the aim of developing a new molecular multiferroics. First, a stable complex of a supramolecular cation rotor constructed from m-fluoroanilinium and [18] crown-6-ether which is a condensation of two cyclohexane rings, and a ferromagnetic manganese-chromium oxalate crosslinked complex. We have established a method for synthesizing plastic crystals and succeeded in producing a single crystal that enables the expression of complex functions. In addition, by changing the type of halogen introduced into the anilinium derivative constituting the supramolecular cation, we succeeded in controlling the molecular motion in the crystal and the physical characteristics expressed. From the above results, we were able to obtain results for developing future development of molecular multiferroics.

| Academic Significance and Societal Importance of the Research Achievements |
マルチフェロイック物質は、電場・磁場双方で制御可能な多値メモリーなどの開発に期待が寄せられており、国内外で無機物を中心に物質探索が数多く行われている。しかし、物質作成に高温高圧などの、特殊な条件が必要な物質が多く、大幅な組成変化を伴う化合物合成は困難である。このような、物質探索に対する自由度が極端に低いマルチフェロイクス開発において、申請者等が開発した安定なハイブリッド型柔粘性結晶の合成法や結晶内分子運動に対する置換基効果の解明は、従来型のマルチフェロイクス開発とは一線を画する材料開発の設計指針を提供する成果として注目され、分子性複合機能材料開発に大きな波及効果をもたらす可能性が高い。
