The search for new high energy-density materials (HEDMs) that would serve as explosives or propellants is an ongoing one.
Recently, we have been interested in certain boron compounds as possible HEDMs (Richard and Ball 2006; Richard and Ball 2007; Janning and Ball 2010) because of the thermodynamic stability of the putative product, [B.sub.2][O.sub.3] However, in part because of the stability of [B.sub.2][O.sub.3] many boron compounds are air-sensitive (Greenwood and Earnshaw 1984).
Many HEDMs contain the nitro (NO ) group (Akhavan 2004), which not only provides oxygen to oxidize other elements in a molecule, but also contains nitrogen atoms, which can react upon decomposition/combustion to form very stable [N.sub.2] gas.
It is worth noting that nitroboroxines can be considered "green" HEDMs because they give off no carbon dioxide upon decomposition or combustion.
