Developing new functional explosives that display high stability,good energy performance,and low sen-sitivity are one of the key directions of energetic materials research.In this work,two-dimensional(2D)Schiff-based energetic covalent organic frameworks(COFs)are prepared based on triaminoguanidine salts with different anions as building blocks.Benefiting from the robust covalent bond in 2D extended poly-gons and strong π-π interactions in the eclipsed interlayers,the synthesized energetic COFs showed higher thermal stability and lower mechanical sensitivity than their precursor salts.More importantly,incorporating triaminoguanidine salts into COFs effectively increase the corrosion resistance to metal un-der high humidity conditions,which is due to the imine moieties in COFs functioning as π acceptors and offering strong bonding with metallic ions.This work provides a new pathway for the development of high-performance energetic materials.
