Research on novel energetic coordination polymers (ECPs) has become increasingly important for energetic materials; numerous ECPs have been reported and found to be potential energetic materials. In this study, 1,2,3-triazole-4,5-dicarboxylic acid 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 the synthesized complexes exhibit excellent thermostability, with decomposition temperatures ranging from 312 to 334 °C, and they show good experimental densities. Additionally, the non-isothermal kinetic parameters and thermodynamic parameters were calculated for all prepared ECPs. The combustion flames 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 component candidates for chlorine-free “green” pyrotechnics.
Macromonomers bearing tridentate 2,6-bis(1,2,3-trizol-4-yl)pyridine (BTP) ligand unit synthesized via CuAAC “click” chemistry in the middle of the chain and two ureidopyrimidinone (UPy) motifs on the ends linked to the central BTP unit via PEGs of various lengths were synthesized and used for the study of gelation both with and without the presence of Eu(III) ions. Various interesting gelation behaviors were found. Gels exhibited various multi-responsive properties, including photoluminescence, mechanoresponsive properties, self-healing abilities, thermorepsonsive properties and chemoresponsive properties. The different gelation abilities and multi-responsive properties for different systems were shown to be resulted from difference in PEG linker lengths and the introduction of orthogonal metal–ligand coordination and hydrogen bonding interactions. The selective responsiveness to different chemicals would allow the development of modular sensory systems that utilize a combination of orthogonal supramolecular interactions.
