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.
