CrystEngComm, Год журнала: 2016, Номер 18(33), С. 6124 - 6133

Опубликована: Янв. 1, 2016

Energetic materials that can store and rapidly release large amounts of chemical energy on demand play a vital role in both military civilian fields. Modern energetic should have high density, heat formation possess molecular stability allow them to be manufactured, stored handled safely. Recently, cocrystallization technology offers promising platform for achieve desired balance between detonation performance low sensitivity. This paper highlights recent developments cocrystals details intermolecular interactions, physical parameters properties. The major part the discussion relates different types including composed molecules solvents, 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20)-based azole-based cocrystals, et al. In addition, resonant acoustic mixing (RAM) technique, bead milling spray flash evaporation technique are also introduced as means large-scale production nanosized cocrystals.

Angewandte Chemie International Edition, Год журнала: 2016, Номер 55(41), С. 12895 - 12897

Опубликована: Сен. 15, 2016

Abstract A family of 3,6‐dinitropyrazolo[4,3‐c]pyrazole‐based energetic compounds was synthesized by using versatile N ‐functionalization strategies. Subsequently, nine ionic derivatives the , N′ ‐(3,6‐dinitropyrazolo[4,3‐c]pyrazole‐1,4‐diyl)dinitramidate anion were prepared acid‐base reactions and fully characterized infrared, multinuclear NMR spectra, elemental analysis. The structures four these further confirmed single‐crystal X‐ray diffraction. Based on their different physical detonation properties, exhibit promising potential as modern materials can be variously classified green primary explosives, high‐performance secondary fuel‐rich propellants, propellant oxidizers.
