Outline of Final Research Achievements

We report the interesting thermal properties of the adamantane-based ionic liquids (ILs). The ion salts with steric molecules such as adamantane carboxylates and imidazolium cations were prepared. We found that assembly of ion pairs to the adamantane core can improve the thermal stability and lower melting temperatures. Finally, the thermally-stable ionic liquids can be obtained based on the steric core. The mechanism study on the thermal properties of synthesized ILs revealed that the tetrahedral-like distribution of ion pairs assisted by the steric core should be of essential for expressing characteristic thermal properties.
