Carbonyl-bridged energetic materials: biomimetic synthesis, organic catalytic synthesis, and energetic performances

Abstract

In order to obtain high-performance energetic materials, in this work, carbonyl groups (C[double bond, length as m-dash]O) have been newly introduced as sole bridging groups in the field of energetic materials. To this end, two tailored green methods for the synthesis of carbonyl-bridged energetic compounds have been developed for the first time. One is a biomimetic synthesis, in which the conversion route of heme to biliverdin has been used to obtain metal-containing energetic compounds. The other one is an organocatalysis, in which guanidinium serves as an energetic catalyst to afford other energetic compounds. Experimental studies and theoretical calculations have shown that carbonyl-bridged energetic compounds exhibit excellent energetic properties, which is promising for the carbonyl group as a new important and effective linker in energetic materials.

Synthesis and Energetic Properties of Trending Metal‐Free Potential Green Primary Explosives: A Review

“…[33] Based on these reasons, synthesis of novel promising metal-free greener primary explosives (consists of only CHON elements) with high performance is required to substitute the LA and LS. [34] Therefore, this paper needs to summarize the latest developments in the synthesis and characterization of various metal-free green primary explosives. Several metal-free greener energetic materials have been synthesized in recent years.…”

Crystal structure of 1,4-bis[5-(2-methoxyphenyl)-2H-tetrazol-2-yl]butane

“…A search of the Cambridge Structural Database (CSD Version 5.40, November 2018; Groom et al, 2016) for bis(tetrazolyl)alkane fragments provided four hits with a methylene bridge [SAVPAJ, SAVPIR (Freis et al, 2017), OYIWOK02 (Feng, Qiu et al, 2016) and UMOJEN (Feng, Bi et al, 2016)] and two with a propylene bridge (SIBFIV, SIBFUH; Wurzenberger et al, 2018). The butylene-bridged examples include a bistetrazolyl copper complex (SIBGIW; Wurzenberger et al, 2018) and three bis(pyridyltetrazolyl)silver complexes (QOKBAV, QOKBEZ, QOKBID; Wang et al, 2014).…”

Self-Assembly Method for Synthesizing High-Dimensional EMOFs with High Stability and Laser Response

“…MOFs with different dimensions have varying physical and chemical properties. On the basis of this knowledge, N-rich energetic materials are combined with metal ions to form energetic MOFs (EMOFs), which are a promising new type of energetic materials. − Some EMOFs have been proven to achieve excellent detonation performance, high thermal stability, and low mechanical sensitivity. Therefore, EMOFs are expected to strike a balance between the energy and safety of explosives. − High-dimensional EMOFs with complex connection patterns typically exhibit good energy performance and stability. − In addition, the energy properties and stability of high-energy ligands exert a crucial effect on the energy and safety properties of EMOFs .…”
