High Energy Density Material Chemistry
Abstract
The overall objectives of this research are the syntheses and characterization of polynitrogen, high-nitrogen and high-oxygen energetic materials, useful as propellants or explosives ingredients. Excellent results were obtained in all areas and are summarized in 38 pubications and 2 patents. The chemistry of N5+ was developed and 13 new N5+ salts were prepared and characterized. It was demonstrated that N5+ cations can be combined with doubly charged anions, thereby doubling the N5+ content of a salt. Furthermore, it was shown that N5+ can be combined with highly energetic counter-ions. Another novel polynitrogen ion, discovered under this program by electrospray ion mass spectroscopy, is the cyclo-N5 anion. Two other novel polynitrogen species, were prepared and characterized. A new method for the processing of nitrogen NMR data with greatly improved signal to noise ratios was developed and successftilly applied to N5+. A large number of novel poiyazides were prepared and characterized. A new concept for liquid monopropellants, based on oxygen-balanced energetic ionic liquids, was developed and successfiilly demonstrated. A new stable reagent, for the introduction of gem-bis NF2 groups was developed. A new solid-gas process, which avoids liquid phase quenching was invented for generating singlet delta oxygen for the COIL laser.
