Research Progress in Energetic Metal-organic Frameworks
Pages: 442-450
Year: Issue:  6
Journal: Chinese Journal of Energetic Materials

Abstract: In recent years,energetic metal-organic frameworks(E-MOFs) have received worldwide research attention due to their promising characteristics of both high energy level and low sensitivity.The design and syntheses of new E-MOFs with new structures,high energy level and excellent safety property have become a research hotspot in the field of energetic materials.Up to now,the energetic organic ligands that have been used for the construction of E-MOFs can be classified into three major categories:small molecular energetic ligands (azide anion and hydrazine),nitrogen-rich heterocyclic ligands (triazole,tetrazole and derivative),energetic ligands with multiple explosophores (e.g.nitro group).According to above classification of three energetic ligands,in this paper,we briefly reviewed the recent advances of E-MOFs from the standpoints of their self-assembly strategies,energy level,and safety issues.After systemically analyzing above advances in the field of E-MOFs,it can be conclude that the rational design and selection of nitrogen-rich multbentate energetic ligand molecules and their self-assembly metal ions are the key to successfully construct novel E-MOFs,since different self-assembly methods will determine the topologies of the E-MOFs'networks and thereby significantly influence the physicochemical properties of the resulting E-MOFs.As a newly emerging class of energetic materials,E-MOFs have exhibited unique properties including high energy level and low sensitivity,demonstrating the important research value and development potential among the applications of solid propellant formulations and laser initiation fields.
