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.
