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

Area of Science:

• Materials Science
• Chemistry

Background:

• Traditional organic synthesis for energetic materials is often multistep and complex.
• There is a need for novel energetic materials with improved safety and performance.

Purpose of the Study:

• To develop a self-assembly approach for constructing novel energetic materials.
• To synthesize and characterize ternary and quaternary energetic assemblies.

Main Methods:

• Utilized a self-assembly strategy to integrate oxidizing and reducing components at the molecular level.
• Assembled bistetrazole or nitrogen-rich ions with nitraminotriazole or dinitraminotriazole to form energetic assemblies.
• Characterized ternary (TNH) and quaternary (TNA-1, TNA-2) assemblies.

Main Results:

• Successfully synthesized ternary and quaternary energetic assemblies using self-assembly.
• TNA-2 demonstrated superior performance among the synthesized materials.
• TNA-2 achieved a high nitrogen-oxygen content (84.3%) and exhibited detonation properties (velocity: 9216 m/s, pressure: 36.7 GPa) rivaling HMX.

Conclusions:

• The self-assembly approach is effective for creating advanced energetic materials.
• TNA-2 represents a promising new energetic material with high performance.
• This method facilitates the development of diverse assembled energetic materials.
