Tetraamino-Driven Hydrogen-Bonding Networks: A Selective Self-Assembly Paradigm for Energetic Materials

Abstract

Hydrogen bonding is crucial in the self-assembly of energetic materials. However, such dynamic networks suffer from selectivity difficulties and are susceptible to multicomponent interference. This work proposed a bioinspired selective approach using 2,5,6,9-tetraamino-pyrazino[2,3-d]pyridazine (TPP). Driven by hydrogen-bonding networks, TPP can form specific stacking modes with different self-assembly components, achieving selective encapsulation. Among them, TPP-HClO4 exhibits superior overall performance compared to the benchmark heat-resistant explosive hexanitrostilbene (HNS).
