Triazene derivatives of (1,x-)diazacycloalkanes. Part VI. 3-({5,5-Dimethyl-3-[2-aryl-1-diazenyl]-1-imidazolidinyl}methyl)-4,4-dimethyl-1-[2-aryl-1-diazenyl]imidazolidines — Synthesis, characterization, and X-ray crystal structure

Abstract: Reaction of a series of diazonium salts with a mixture of formaldehyde and 1,2-diamino-2-methylpropane affords the 3-({5,5-dimethyl-3-[2-aryl-1-diazenyl]-1-imidazolidinyl}methyl)-4,4-dimethyl-1-[2-...

Uranium determination in industrial effluents by voltammetric method using triazene 1-oxide as an alternative binder

Abstract: This study reports for the first time the uranium (U) determination in industrial effluents by differential pulse adsorptive stripping voltammetry using triazene compound as a binder. Analyses were performed in 0.01 mol L−1 acetate buffer (pH 4.4), and the binder used was 1-methyl-3-(p-carboxyphenyl)triazene 1-oxide with the complex reduction peak at − 0.38 V. A detection limit of 0.06 and a quantification limit of 0.20 µg L−1 were achieved. The recovery values of spiked samples were between 80 and 100% (RSD less than 10.4%), and the concentration range from 0.35 to 7 μg L−1 was linear (r2 = 0.99). The values of U quantified in the samples INB-01, INB-02, INB-03 and INB-04 were 10.74, 30.58, 58.21 and 956.56 μg L−1, respectively. The complex formed is irreversibly reduced on the electrode surface, with the transfer of two electrons, and the process is controlled by diffusion. Additionally, it is suggested that the U(VI) center coordinates itself to the N and O atoms of six triazene groups forming stable five-membered rings with coordination number equal to twelve and icosahedral geometry.

Polymers with Triazene Units in the Main Chain

Abstract: Several monomeric and polymeric triazenes have been synthesized and characterized by common methods such as 1H NMR-, IR-, Raman-, UV-spectroscopy, DSC, and GPC. Their thermolysis, photosensitivity, and the effect of H3O+ on their stability have been studied in detail, since those characteristics are very important for an application of these compounds in microlithography.

Boosting Laser-Ignited Combustion Performance of Energetic Materials with Low Sensitivity: Integration of Triazene-Bridged Triazole with Oxygen-Rich Moieties via Noncovalent Self-Assembly

Abstract: It has long been a driving force in the development of energetic materials to hunt for novel high-energy density materials (HEDMs) with high energy and good stability. Recently, the noncovalent self-assembly strategy of energetic anions and cations to generate HEDMs is an effective strategy for introducing an oxidizer and fuel separately into the energy system. In this study, bis(1,2,4-triazolyl)triazene containing triazene (−N═N═NH−) and oxidant molecules (i.e., HNO3 and HClO4) were selected as high-energy ions to develop new high energy materials by using noncovalent self-assembly. The experimental results showed that three exemplary compounds possess excellent detonation pressure and detonation velocity (PC–J: 22.8–29.3 GPa and D: 7425–8135 m s–1), which are comparable to the classical explosive trinitrotoluene (TNT) (PC–J: 19.5 GPa and D: 6881 m s–1) as well as 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX) (PC–J: 34.9 GPa and D: 8795 m s–1). Moreover, 1 and 3 exhibit low mechanical sensitivities (IS: 40 J and IS: 70 J). Thus, 1 and 3 have great potential as insensitive energetic materials. Especially, these energetic assemblies have excellent laser-ignited combustion properties and can be used as candidates for low sensitivity propellants.
