A solvent-free dense energetic metal–organic framework (EMOF): to improve stability and energetic performance via in situ microcalorimetry

Abstract

It is a tremendous challenge to prepare solvent-free dense energetic metal-organic frameworks (EMOFs), hence also to improve their stability and energetic performance. In this study, based on in situ microcalorimetry, an interpenetrating EMOF without solvent molecules, [Cu(tztr)] (1, Htztr = 3-(tetrazol-5-yl)triazole) was obtained, possessing high stability (T = 360 °C) and outstanding energetic properties (ΔH = 7.53 kcal cm, D = 8.429 km s, P = 40.02 GPa).

Metal–Organic Frameworks as Fuels for Advanced Applications: Evaluating and Modifying the Combustion Energy of Popular MOFs

“…[1][2][3][4][5][6][7][8][9][10] Recently, MOF formation was reported as a route to generate new energetic materials, by using energetic molecules as ligands. [11][12][13][14][15][16] Our group 17 has demonstrated a MOF-based strategy for generating new hypergolic solid fuels, i.e. fuels that ignite simultaneously upon contact with an external oxidizer.…”

Structurally uneasy but kinetically stable nitrogens in 1,3‐disubstituted cyclotetrazenes: Viable high‐energy‐density materials

“…These designed porous structures containing H, C, N elements are quite similar to the covalent organic frameworks (COFs) . Inspiringly, the high‐energy metal organic frameworks (HE‐MOFs) have been recently developed . It is our expectation that the presently designed HE‐COFs based on the novel organic energetic N 4 unit would be realized in near future.…”

Nanoarchitectonics meets cell surface engineering: shape recognition of human cells by halloysite-doped silica cell imprints

“…Relatively solid microbial cells with cell walls as well as soft mammal cells (including human cells) were used in cell surface engineering [15]. Surface-engineered cells have found applications in whole-cell biocatalysis [16], cell therapy [17], magnetic cell delivery [18], fabrication of multicellular assemblies [19], cell protection [20–21], biosensors [22] and tissue engineering [23]. Shells derived from cells templates offer other fascinating opportunities due to their cell-mimicking geometries, for example, a novel class of bioinspired colloid particles was fabricated recently.…”
