Coordination Polymers with High Energy Density: An Emerging Class of Explosives

Abstract

Coordination polymers (CPs) have recently emerged as a promising class of high energy materials useful for the synthesis of tailored energetic materials. CPs have shown potential to improve energetic performance relative to conventional organic energetic materials with regard to density, oxygen balance, sensitivity, and heat of detonation. Thus far, a variety of energetic linkers have been applied, and success has been achieved across a number of structure classes including nitrogen-rich heterocycles and azides. Here, the current progress in the field of energetic CPs, both from the standpoint of structure and properties, is reviewed, and a perspective on current challenges and promising future directions for the field are delineated. Inasmuch as structure/function relationships have been elucidated for CPs with particular applications in mind, these are discussed as well as shortcomings in experimental work required to firmly establish predictive principles within the realm of energetic materials.

Study of Six Green Insensitive High Energetic Coordination Polymers Based on Alkali/Alkali‐Earth Metals and 4,5‐Bis(tetrazol‐5‐yl)‐2 H‐1,2,3‐triazole

“…[10][11][12][13][14][15][16][17][18] As an ew access to IHEs, energetic coordination polymers (ECPs) [19][20][21][22][23][24][25][26][27][28][29][30][31][32] are emerging with both excellent safety and high energy,ast heir specific composition(organicsand inorganics) and various dimensionalities (1D, 2D, and3 D) give strong structuralr einforcements and extensive coordination networks, in whichs horter covalentc oordination bonds will lead to higherd ensity ands tability.

Synthetic, Crystallographic, and Computational Studies of Extensively Hydrogen Bonded Bilayers in Thermally Stable Adamantane Hydroperoxides

“…Matzger et al. have also identified that the hydrogen‐bond functionality acts as an important interaction in peroxides and energetic materials . The principal binding forces in these crystals are hydrogen bonds.…”

Self-assembled energetic coordination polymers based on multidentate pentazole cyclo-N5−

“…Nitrogenrich compounds constitute a large family of interesting compounds, which are certainly no less active than the traditional CHON energetic materials [4,5]. It is worth noting that they have boosted the development of energetic salts [6][7][8], energetic coordination polymers (CPs, also defined as energetic metal organic frameworks (MOFs) in some cases) [9][10][11], and energetic co-crystals [12,13], and thus significantly expanded the range of energetic materials.…”
