Salts Dissolved in Salts: Ionic Liquid + inorganic salt mixtures

DOI

Ionic liquids (ILs) are low melting point organic salts that until recently were thought to have homogeneous microstructure. In recent SANDALS research,1 we showed pure ILs are nanostructured, and self-assemble into bicontinuous phases due to strong ion-ion interactions. Subsequent SANDALS data revealed a simple inorganic salt (6wt% LiNO3) is ¿structure-making¿; IL nanostructure is enhanced as Li+ ions template more-pronounced charge segregation in the bulk.2 In this proposal, we will examine IL nanostructure as a function of dissolved salt by studying IL+inorganic salt mixtures (6wt% Mg[NO3]2, Al[NO3]3, Zn[NO3]2) and compare the structures obtained to the pure ILs.1 This will test concepts of ¿structure-making¿ and ¿structure-breaking¿ ions in non-aqueous solvents that are similar to, but distinct from, Hofmeister effects in water as IL bulk structure is an order of magnitude larger.
