Bis(borano)hypophosphite-based ionic liquids as ultrafast-igniting hypergolic fuels

A family of hydride-rich bis(borano)hypophosphite-based ionic liquids was developed, which showed good water stability at room temperature and unexpected hypergolic reactivity with oxidizers. These ionic fluids have exhibited the shortest ignition delay times so far, demonstrating their application potential as hypergolic fuels or additives in liquid bipropellants.
