Application of 1- and 2-Propargyl-Tetrazole in Laser-Ignitable Energetic Coordination Compounds

Assembly of thermostable fused compounds with oxidizers for laser-ignited energetic materials

“…Overall, the introduction of high-energy oxidizers enhances the burning performance of the parent material, which is similar to the report of Klapötke et al 31 Through comparison, it is found that the effect of ClO 4…”

Energetic copper(ii) quadridentate chelate: a novel green laser-sensitive primary explosive

“…In previous studies, the required performance of LSPEs based on energetic complexes could be obtained by regulating their three building blocks. Regarding the anionic constituents, apart from a few instances where chlorate (ClO 3 − ), bromate (BrO 3 − ), and azide (N 3 − ) ions are utilized, the overwhelming majority of LSPEs feature perchlorate ions (ClO 4 − ), [13][14][15][16][17][18] which are acknowledged worldwide as priority-controlled pollutants. Therefore, the challenge in the field of LSPEs not only needs to solve the contradiction between the initiation threshold and safety performance but also get rid of other obstacles, such as the use of substances harmful to the environment and humanity.…”

“…19 Fortunately, Stierstorfer et al successfully prepared an acid ion-free complex [Cu(H 2 TNPG) 2 (2-PryTz) 4 ] with excellent performance in 2023 using trinitrophloro-glucinol (H 3 TNPG) and 2-propargyl-tetrazole (2-PryTz) as double ligands, which could be reliably initiated by laser. 18 Over the past decade, specific monodentate complexes with low laser-initiation thresholds have shown significant potential in LSPEs. These complexes are typically self-assembled of central metal, nitrogen-rich ligands, and anions, and can be reliably initiated by designated laser wavelengths (Scheme 1a).…”
