Full-Nitro-Nitroamino Cooperative Action: Climbing the Energy Peak of Benzenes with Enhanced Chemical Stability
Siping Pang reports on a new strategy to design an unprecedented type of fully nitrated benzene.
Explosive organic materials – such as nitroglycerine, HMX or nitrocellulose – are extremely important for a number of civil and commercial applications, besides those related to military use, for example in mining or in engineering. Polynitrobenzenes are well-known high-energy-density materials, which contain oxidizers (nitro groups) and fuel components (benzene ring) within a single molecule and generate energy rapidly through self-redox reactions. Generally, the energy of these materials progressively increases with an increasing number of nitro groups, but their stability follows the opposite trend. To date, striking a balance between energy and chemical stability, as well as further increasing the energy while simultaneously improving the stability of polynitrobenzenes, is a significant challenge in the area of novel HEDMs. To overcome this challenge, the group of Professor Siping Pang at the Beijing Institute of Technology (P. R. of China) recently proposed an interval full-nitro-nitroamino cooperative strategy to design an unprecedented type of fully nitrated benzene, 1,3,5-trinitro-2,4,6-trinitroaminobenzene.
