In this work, we prepared and comprehensively characterized four novel iodocuprate-containing ionic liquids, CuILs 1-4. In addition to their interesting molecular structures and physical properties CuILs exhibited capability to efficiently promote hypergolic reactions between boron-containing [EMIM+][H3BCN-] and [MIM][BH3] fuels and a highly concentrated H2O2 (95%) oxidizer. The most promising promoter CuIL 3 has the decomposition temperature well above the decomposition temperature of the fuels, was stable in promoter-in-fuel mixtures for weeks and showed ignition delay times down to 14 ms. We believe that further development of our new iodocuprate ionic liquids can lead to promising green H2O2-based bipropellant systems for space applications.
