被引用回数：27 パーセンタイル：84.57(Chemistry, Multidisciplinary)Three-dimensional arrays of dipolar rotors were constructed as single crystals of molecular gyrotops, which are macrocage molecules with a bridged dipolar rotor. In this study, we synthesized novel molecular gyrotops with a five-membered heteroring, i.e., furan-diyl, thiophenediyl, and selenophene-diyl, and investigated the temperature-dependent orientation and rotation of the dipolar rotors inside the crystal.

Since the synthesis and characterization of lithium cation endohedral metallofullerene(lic fullerene), several investigations have been performed on the application of lic fullerene to the functional materials. However, there has been no study on the application of the "lic fullerene" to the energy storage systems. In the present work, we investigated the energy storage characteristics of Li@C capacitor. The energy stored by Li@C/o-DCB capacitor was greater by several times than that stored by TBA/o-DCB capacitor under the same conditions. This result indicated that TBA ions undergo solvation and the size of the solvated TBA would be larger than that of Li@C ions. Moreover, the charging speed of Li@C/o-DCB capacitor was faster than that of TBA/o-DCB capacitor. This would originate from the shape of Li@C ion having a spherical structure.
