Outline of Final Research Achievements

We developed the interesting properties of the POSS-based ionic liquids (ILs). The ion salts with steric molecules such as POSS carboxylates and imidazolium cations were prepared. We found that assembly of ion pairs to the POSS 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 cubic-like distribution of ion pairs assisted by the steric core should be of essential for expressing characteristic thermal properties. Furthermore, we also prepared the series of luminescent POSS with ionic side-chains. Unique optical properties of these molecules were found.
