Tunable mechanics and energetics in structurally diverse TNPG-based metal organic networks.

ABSTRACT: Developing high-energy materials that are powerful yet safe requires a careful balance between thermal stability, mechanical strength, and detonation performance. While metal coordination is a known strategy to improve the thermal stability of energetic compounds like trinitrophloroglucinol (TNPG), mono-metallic networks often suffer from diminished detonation performance and increased sensitivity. This work introduces a new class of hetero-metallic metal-organic networks, MM'-TNPG (M/M' = Li, Na, K), that harmonizes all critical performance parameters, including enhanced thermal stability, reduced sensitivity, and high detonation output. Particularly, we present the first systematic correlation between mechanical properties evaluated via nanoindentation and detonation performance,
