Xu, Jian-Gang published the artcileEnergetic azide-based coordination polymers: Sensitivity tuning through diverse structural motifs, Synthetic Route of 1455-77-2, the main research area is energetic azide based coordination polymer structural analysis sensitivity.

Energetic coordination polymers (ECPs), as a new class of energetic materials (EMs), have attracted extensive attention in recent years. However, controllable modulation of mech. sensitivities and the establishment of structure-function theor. models of ECPs to meet different applications remain great challenges. Herein, we designed and synthesized four azide-based ECPs, [Cd2(N3)2(datz)2]n 1 (Hdatz = 3,5-diamino-1,2,4-triazole), [Cd(N3)2(brt)2]n 2 (brt = 4,4â€?bi-1,2,4-triazole), [Cd(N3)2(btzp)]n 3 (btzp = 1,3-di(tetrazol-1-yl)propane), and [Cd2(N3)4(btzb)]n 4 (btzb = 1,4-bis(tetrazol-1-yl)butane). Because of the existence of consolidated network structures, high-energy linkers, and diverse structural motifs, compounds 1-4 exhibit reliable thermal stabilities, tunable mech. sensitivities, and considerable heats of detonation (ΔHdet) with the ΔHdet values of 3.390, 3.412, 3.947 and 4.504 kJ·g-1, resp., which are two times higher than those of com. LA (lead azide) and the reported AgMtta (AgMtta = [Ag(Mtta)]n, HMtta = 5-methyl-1H-tetrazole). The sensitivity measurements demonstrate that the sensitivity toward impact of 1-4 displays in the following order: 1 (>40 J) â‰?2 (8 J) < 3 (2.5 J) < 4 (2 J). In particular, compound 1 features scarce insensitivity compared with sensitive 2, 3, 4 and most of known azide-based EMs. Furthermore, theor. calculations, structural analyses, and exptl. results revealed that the different sensitivities of the four ECPs are mainly dependent on two different structure models for the first time. The insensitive 1 is ""body frame structure"" model, while the sensitive 2-4 belong to ""non-body frame structure"" model. Our study enlightens new insights into structures behind mech. sensitivities for optimizing advanced EMs. Chemical Engineering Journal (Amsterdam, Netherlands) published new progress about Explosives. 1455-77-2 belongs to class isoquinoline, name is 3,5-Diamino-1,2,4-triazole, and the molecular formula is C2H5N5, Synthetic Route of 1455-77-2.

Low cost, high yield, good safety, and simple synthesis process are the problems that must be solved in the engineering preparation of energetic compounds, even beyond the pursuit of high energy level to some extent. In this work, a novel 5,6-fused energetic mol. 2-nitro-[1,2,4]triazolo[1,5-a][1,3,5] triazine-5,7-diamine (NTTD) was designed and easily obtained. By the introduction of oxidants (HNO3 and HClO4) and high-energy groups (-NHNO2), the derivatives of NTTD were prepared, some of which exhibited good comprehensive properties. Importantly, NTTD features excellent thermostability and low mech. sensitivities. The whole preparation process has advantages of simple operation, short time, cheap and simple reagents, good repeatability, and high yield, which are conducive to large-scale preparation, indicating that NTTD can be a potential candidate of heat-resistant and insensitive explosives.

Chen, Dongxu published the artcileIntroduction of the acylamino group to bridged bis(nitroamino-1,2,4-triazole): a strategy for tuning the sensitivity of energetic materials, Formula: C2H5N5, the main research area is energetic material nitroaminotriazole acylamino introduction sensitivity tuning.

In this work, the acylamino group has been introduced into energetic materials to build acylamino-bridged bis(1,2,4-triazole) 3 and its nitration derivative 4. Both 3 and 4 were thoroughly characterized via spectroscopic and structural methods. In addition, their sensitivities toward friction and impact were determined and the energetic performances of 3 and 4 were calculated using the EXPLO5 code. Compound 3 is insensitive to mech. stimulation (IS: 40 J, FS: 320 N). Besides, compared with the C-C-bonded compound DNABT (IS: 3 J, D: 8355 m s-1) without any bridging group, 4 achieves a balance between the sensitivity (IS: 18 J, FS: 200 N) and the detonation velocity (D: 8564 m s-1). The effect of introducing an acylamino group into 3 and 4 was elucidated using HOM: O-LUMO anal. and the anisotropy of the induced current-d. method.

Gao, Tong published the artcileMechanochemical synthesis of three-component metal-organic frameworks for large scale production, Category: isoquinoline, the main research area is zinc amino triazolate isophthalate MOF mechanochem preparation gas adsorption; XPS zinc amino triazolate isophthalate MOF.

Two pillared-layer metal-organic frameworks with pcu network were synthesized by the mechanochem. reaction of three components (ZnO, 3-amino-1,2,4-triazole (Hatz) or 3,5-diamino-1,2,4-triazole (Hdatz), and isophthalic acid (H2ipa)) at room temperature with space-time yield up to 4800 kgm-3 day-1. The mechanochem.-synthesized [Zn2(atz)2(ipa)] (Zn-atz-ipa) and [Zn2(datz)2(ipa)] (Zn-datz-ipa) exhibit the high purity and porosity with BET surface areas of 655 and 572 m2g-1, resp., which are comparable with those synthesized by the traditional solvothermal method. In C2H4/C2H6 (volume/volume = 1/1) breakthrough experiment, Zn-datz-ipa can preferentially adsorb C2H6 over C2H4, showing a great potential for one-step purification of C2H4. In addition, this mechanochem. method can be scaled up to 100 mmol magnitude with single-pass production up to 20.0 g.

Organic arsenic compounds in the environment are a global threat to human health. This threat has created the urgency to develop highly efficient adsorbents with both high adsorption capacity and versatile removal of different arsenic compounds A novel 1D zinc(II) coordination polymer, formulated as Zn2(datrz)2(bpy)Cl2 (BUC-70) (datrz = guanazole, bpy = 4,4′-bipyridine), was successfully synthesized through slow evaporation at room temperature BUC-70 exhibited an excellent adsorption capacity toward p-arsanilic acid (p-ASA) and roxarsone (ROX) in water, which could be ascribed to As-O-Zn bonding interactions and strong hydrogen-bonding interactions between the organic arsenics and BUC-70. The maximum adsorption capacities toward p-ASA and ROX were 738 and 937 mg·g-1, resp. BUC-70 was effective in the removal of p-ASA and ROX at low concentrations (<5 mg·l-1) from the simulated p-ASA and ROX wastewater. Furthermore, the as-synthesized BUC-70 exhibited good adsorption property toward p-ASA and ROX in wastewater simulated by lake water and tap water. After adsorptive treatment using BUC-70, the concentrations of both p-ASA and ROX were lower than the required concentrations of the drinking water standard of the World Health Organization and the surface water standard of China.

Gu, Lin published the artcileInsights into the role of an Fe-N active site in the oxygen reduction reaction on carbon-supported supramolecular catalysts, Product Details of C2H5N5, the main research area is iron nitrogen active site oxygen reduction carbon supramol catalyst.

In this study, a nitrogen-containing ligand supramol. named PPYTZ was successfully synthesized using 2,6-pyridinedicarboxylic acid chloride and 3,5-diamino-1,2,4-triazole in order to carry out oxygen reduction reaction (ORR). Such a polymer provides abundant coordination sites for iron ions, and the PPYTZ-Fe/C composite catalyst was formed with the PPYTZ-Fe complex loading on the surface of Vulcan XC-72 carbon. The phys. characteristics and ORR performance of the composite catalysts were characterized systematically via various relevant techniques, and their catalytic activity and reaction mechanism were evaluated and compared. The results showed that the catalytic activities and the reaction mechanism of ORR were highly dependent on the formation of an Fe-N unit. Accordingly, the PPYTZ-Fe/C catalyst containing Fe-N active sites exhibited high ORR catalytic activity (an onset potential of +0.86 V vs. RHE) in 0.1 M KOH. Such an Fe-N catalyst can accelerate the adsorption of O2 and increase the limiting c.d. (from 2.49 mA cm-2 to 4.98 mA cm-2), optimizing the ORR catalytic process from a two-electron process to a four-electron process (an n value of 3.8).
