Synthesis and investigation alkaline energetic coordination polymers based on 1,2,3-triazole-4,5-dicarboxylic acid for green component of pyrotechnic

Research on novel energetic coordination polymers (ECPs) is becoming increasingly important for energetic materials, numerous ECPs were reported and found to be potential energetic materials. In this study, 4,5-dicarboxylic-1,2,3-triazolean was synthesized by an innovative synthetic route and its complexes with alkali metals (Li, Na, K, Rb, Cs) were synthesized and comprehensively characterized, by single-crystal X-ray diffraction, elemental analysis, FT-IR and mass spectra. Most of synthesized complexes exhibit excellent thermostability, with decomposition temperatures ranging from 312 to 334 °C, and show good experimental densities. Additionally, the non-isothermal kinetic parameters and thermodynamic parameters for all prepared CPs were calculated. The combustion flame of the five complexes are in a range of characteristic flame colors (from purple-red to blue). At the same time, all the synthesized CPs have remarkable insensitivity toward friction and impact (FS > 360 N, IS > 40 J), which makes them promising components candidates for chlorine-free “green” pyrotechnic.
