Many energetic materials synthesized to date have limited applications because of low thermal and/or mechanical stability.T his limitation can be overcome by introducing structural modifications such as abridging group.Inthis study, as eries of 1,3,4-oxadiazole-bridged furazans was prepared. Their structures were confirmed by 1 Hand 13 CNMR, infrared, elemental, and X-ray crystallographic analyses.T he thermal stability,f riction sensitivity,i mpact sensitivity,d etonation velocity,and detonation pressure were evaluated. The hydroxylammonium salt 8 has an excellent detonation performance (D = 9101 ms À1 ,P = 37.9 GPa) and insensitive properties (IS = 17.4 J, FS = 330 N), which show its great potential as ah igh-performance insensitive explosive.U sing quantum computation and crystal structure analysis,t he effect of the introduction of the 1,3,4-oxadiazole moiety on molecular reactivity and the difference between the sensitivities and thermal stabilities of mono-and bis-1,3,4-oxadiazole bridges are considered. The synthetic method for introducing 1,3,4oxadiazole and the systematic study of 1,3,4-oxadiazolebridged compounds provide at heoretical basis for future energetics design.

A new member of the 2D carbon–nitrogen-rich family of nanomaterials was synthesized by polycondensation of triaminoguanidine hydrochloride with glyoxal. This new polymer (TAGP) and its transition metal complexes (TAGP–Ms) were found to be energetic and insensitive.

New iodocuprate-containing ionic liquids with high thermostability were designed, prepared and evaluated as hypergolic reaction promoters between an energetic ionic fuel and a H2O2 “green” oxidizer.
