| Research Abstract |
For the most typical ionic liquids, alkylimidazolium ionic liquids, we have found from the heat capacity measurements that the ionic liquids are realized for the cations with the alkyl-carbon number larger than 2 and exhibit glass transitions around 200K. From the neutron diffraction and quasielastic neutron scattering measurements, it was revealed that ionic liquids have domains and their motions are slower than 100ns. It is also shown that ionic liquids exhibit the ionic motions related to the glass transitions and the alkyl-chain motion with ps-order. It is summarized that ionic liquids have spatially and dynamically hierarchical structures.
