Enhancing Energetic Performance of Multinuclear Ag(I)-Cluster MOF-Based High-Energy-Density Materials by Thermal Dehydration

Abstract

It is an enormous challenge to construct high-energy-density materials meeting simultaneously requirements of high energy and excellent stability. In this work, the reaction of a Ag(I) ion with a nitrogen-rich ligand, 1H-tetrazole-5-acetic acid (H 2 tza), leads to a novel Ag7-cluster metal−organic framework, [Ag 7 (tza) 3 (Htza) 2 (H 2 tza)(H 2 O)] (1), with remarkable highenergy content, stability, and insensitivity. Dramatically, the heatingdehydrated process of 1 produces a new stable energetic material, [Ag 7 (tza) 3 (Htza) 2 (H 2 tza)] (1a), which features superior energy and undiminished safety performance compared to those of 1.

A dual-sensitized luminescent europium(iii) complex as a photoluminescent probe for selectively detecting Fe3+

“…In principle, the data extracted from the package tend to zero, responding to the optimal geometry, whereas a greater value presents a major deviation from the optimal polyhedron. 27 As shown in Table S2, † the calculation indicates that Eu III centers are best described as eight-coordinated square antiprism geometry (CshMs parameters: 0.626).…”

“…10 However, these inert water molecules have a negative effect on the detonation performance of metallic cyclo -N 5 − compounds. 11 In these complexes, the thermal dehydration process meant that the thermal stability of the skeleton becomes worse and the mechanical sensitivity increases, leading to a great risk in the synthesis and application of explosives. 9 As common energetic ligands of metal coordination polymers, the structures of small organic molecules (NH 2 –NH 2 , NH 2 OH, NH 3 , H 2 O 2 , etc. )…”

A New Energetic Complex: Synthesis, Structure, and Combustion Catalysis Performance

“…The design and preparation of energetic materials that combine high performance and low sensitivity have been widely studied for military and civilian applications over the last decades. 1,2 Nitrogen-rich heterocycles, featuring high nitrogen content and heats of formation, can generally derive energy from ring or cage strain and the oxidation of their carbon backbone to mainly yield environmentally friendly N 2 molecules as end-product of propulsion or explosion. [3][4][5][6] Given the generation of gasses, these derivatives show potential applications as promising materials in explosives, solid propellants, and other thermal decomposition and combustible systems.…”
