From mono-rings to bridged bi-rings to caged bi-rings: a promising design strategy for all-nitrogen high-energy-density materials N10 and N12

Abstract: The research of all-nitrogen compounds has been always a hot topic in nitrogen chemistry and high-energy-density material communities. Today’s research mainly focuses on acyclic and monocyclic all-nitrogen derivatives, while the...

“…When enduing cyclo-N 5 À with nitroxide coordinate bonds, nine cyclo-N 5 O À salts exhibit high contents of nitrogen and oxygen (82.94% $ 100%), and their oxygen balances (based on CO) all substantially improved. Among them, the OB co of hydroxylammonium salt A1 is 0%, which is equal to high-performance explosive RDX h Lang et al [38] i Shen et al [40] j Lang et al [39] and HMX. Moreover, B1-B3 exhibit very positive oxygen balances, with the values of 18.58%, 18.58%, and 31.37%, respectively.…”

“…In terms of the above issues, all-nitrogen energetic materials have become a research hotspot, which are able to release huge energy by breaking the N-N (159.9 kJ mol −1 ), N = N (418.2 kJ mol −1 ) bonds in structure and forming N≡N (946 kJ mol −1 ) ( Bondarchuk, 2020 ; Lang et al, 2021 ). However, the synthesis of all-nitrogen compounds is very difficult, resulting in extremely slow development.…”

“…[1][2][3] Poly-nitrogen compounds as a unique branch of energetic materials have been a hot topic, due to the high nitrogen contents and high heats of formation. [4][5][6] These compounds are able to release huge energy from the breaking of the N-N (159.9 kJ mol À1 ) and NQN (418.2 kJ mol À1 ) bonds in the structure and the formation of NRN (946 kJ mol À1 ). 7,8 Until now, the experimental research on poly-nitrogen materials has mostly focused on ionic compounds, such as N 5 + and cyclo-N 5 À derivatives, [9][10][11][12][13] while research studies on covalent compounds N x (2 o x r 60) have been extremely hard and developed slowly.…”
