Carbon skeleton: route to investigate high-performance insensitive energetic materials

Abstract

Over the past century, the search for high-performance insensitive energetic materials (HIEMs) has been a highly challenging task in the field of energetic materials. Herein, based on a five-membered carbon skeleton, a new structural framework, 4-amino-3,5-dinitrocyclopentane-1,2-dione, was synthesized through an interesting ring contraction reaction. Its derivatives (3–8) meet nearly all of the significant criteria of HIEMs for commercial applications: high density, good denotation performance, simple synthetic routes, low production costs, mild preparation conditions, and simple post-processing. Both excellent physiochemical properties and facile synthesis indicate the great application potential of this new carbon skeleton and its derivatives in the field of energetic materials.
