The Synthesis and Properties of a Series of Energetic Coordination Polymers Based on Azole Derivatives

The coordination polymers based on azole ligands are one of the most attractive energetic materials at recent years because of their tunable structures, high energy and low sensitivity. In this work, three kinds of azole ligands, 1,2,4-triazole, tetrazole and 5-aminotetrazole, were chosen to construct series of metal organic frameworks with different metal ions such as Zn2+, Cd2+ and Cu2+. Furthermore, These materials have been measured with thermogravimetry, differential Scanning Calorimeter and oxygen bomb tests, which show that the stabilities of the coordination polymers and densities have been enhanced obviously. The enthalpies of formation could be affected by the accumulation between suitable metal ions and energetic ligands, it is instructive for the synthesis of high energetic coordination polymers in future.
