Investigating self-organisation in ionic liquid mixtures containing fluorous and aliphatic cations
We are investigating ionic liquid (IL) mixtures prepared from cations with both fluorocarbon and hydrocarbon chains for use in supported IL-phase (SILP) catalysis to improve catalyst performance and stability. In SILPs, a thin IL film containing a homogeneous catalyst is deposited on a porous support to produce a pseudo-heterogeneous catalyst. The bulk liquid structure of the IL is important for SILP catalysis, as it strongly affects the microenvironment of catalyst molecules dissolved in the IL. As fluorous and aliphatic chains have different natures, their self-organisation in a range of selected IL mixtures will lead to interesting bulk structure and properties and these can be used to promote the ideal conditions for different catalytic reactions. Small-angle scattering, combined with contrast variation through selective deuteriation, will allow us to understand the relationships between structure and composition in these systems. This will form the basis for a more rational design of ILs for applications in SILPs.
