| Outline of Final Research Achievements |
New trinuclear metal complexes with unique macrocyclic structures have been obtained. These complexes form capsule conformations with a large cavity by aggregation of enantiomer-pairs in crystal packing. In this study, we performed the dynamic controls of the capsule conformation of these trinuclear complexes which prepared as magnetic ionic liquids. The complex including Mn(III)2Cu(II) hetero-metal core is obtained as an ionic complex, which show typical molar conductivity for 1:1 electrolytes. In order to isolate pure ionic liquid, we prepared smaller trinuclear complexes by using another tridentate ligand. The counter ions of this ionic compound have been exchanged by bis(trifluoromethanesulfonyl)imide anions, then viscous oily substance has been obtained. The analyzed formula for this liquid is represented as [Mn3(L)3(O)(MeOH)3](TFMSI). The obtained compound is a new magnetic ionic liquid. It is suggested the obtained ionic liquid can be applied as new magnetic fluid.
