Constructing High-Energy Materials by Self-Assembly of Oxidizing and Reducing Components

Abstract

Different from traditional multistep organic synthesis methods, this study employs a self-assembly approach to integrate high-energy oxidizing components and nitrogen-rich reducing components via weak interactions within the same molecular structure, thereby constructing energetic assemblies. Reducing components bistetrazole or nitrogen-rich ions and oxidizing components nitraminotriazole or dinitraminotriazole were assembled to obtain ternary assembly (TNH) and quaternary assemblies (TNA-1 and TNA-2). Among them, TNA-2 exhibits the best overall performance. TNA-2 possesses a combined nitrogen–oxygen content as high as 84.3%, with a detonation velocity (9216 m s–1) and detonation pressure (36.7 GPa) comparable to those of traditional high-energy explosive HMX. This work presents a self-assembly approach that will facilitate the synthesis of more new types of assembled energetic materials.
