Coordination polymerization of nitrogen-rich linkers and dicyanamide anions toward energetic coordination polymers with low sensitivities

Abstract

The design and synthesis of energetic materials (EMs) with high energy and reliable stabilities has attracted much attention in the field of EMs. In this work, we employed a strategy...

Preparation of High-Energy ECPs by Retaining the Coordination Ability of Carbohydrazide Groups

“…In addition to the theoretical prediction and analysis of the explosive performance of ECPs-1 (shown in Table ), we also used more intuitive characterization methods to evaluate its performance, including thermal stability testing, laser ignition testing, and high-efficiency destruction experiments based on lead plates. , …”

“…In addition to the theoretical prediction and analysis of the explosive performance of ECPs-1 (shown in Table 1), we also used more intuitive characterization methods to evaluate its performance, including thermal stability testing, laser ignition testing, and high-efficiency destruction experiments based on lead plates. 24,25 First, due to the potential destructive nature of ECPs-1, we have improved and conducted traditional hot-needle (HN) testing: the test samples were spread in a powder state on filter paper, which was then ignited to ignite ECPs-1 using residual heat from the filter paper. The test results were in good agreement with our predictions.…”

The combined effect of pyrazole and amino groups: preparation of novel energetic coordination compounds with high ClO4− content

“…Because of their special structure and excellent performance, energetic coordination compounds (ECCs) have also become a research hotspot. 12 They can be roughly divided into four types based on the presence of a ligand, the number of metals, and the presence of external anions. The simplest type is formed by the combination of a ligand and a single metal, such as [Co(OH-Tz) 2 (H 2 O) 4 ] n (OH-Tz: hydroxytetrazole).…”

Refinement of sensitive azides via in situ generated azole-based metal–organic frameworks towards stable energetic materials

“…Energetic materials (EMs) are defined as a series of metastable substances storing large amounts of energy in the form of chemical bonds in a condensed phase, playing a pivotal role in civilian applications and military affairs. [1][2][3][4] Developing highperformance EMs with excellent thermal stabilities and reliable sensitivities has become a predominant research goal in the field of EMs, which can largely broaden their application range. 5,6 Generally, the conventional strategy to improve energy densities is to increase high energy components directly, including N 3 − , ClO 4 − , -NO 2 , furazan and N-rich heterocyclic rings.…”

“…[7][8][9] However, the sensitivity of EMs would always increase exponentially with the enhancement of energy. 2 For instance, commercial 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) is equipped with more powerful detonation performance than that of 2,4,6-trinitrotoluene (TNT), while the mechanical stimulation of RDX is much more sensitive than that of TNT. Therefore, leading innovations of the next generation of EMs not only chase high energy densities, but also focus on a combination of design strategies, crystallography, and chemistry to develop EMs with enhanced energy densities and reliable sensitivities.…”
