STRUCTURE AND PROPERTIES OF NOVEL ENERGETIC COORDINATION COMPLEXES AND THEIR POTENTIAL AS MAGNETICALLY SWITCHABLE EXPLOSIVES

In the field of energetics, much effort is focused on the development of safe, high performance energetic materials for use in military and civilian sectors. An effective explosive must possess good energetic properties such as high energy density, detonation velocity, and detonation pressure. Such materials must also be insensitive to physical initiation stimuli such as impact, friction, electrostatic discharge, and heat to allow for the safe synthesis, transportation and storage of the energetic material. To develop explosives with both high performance and safety metrics, this work seeks to create novel high-energy density energetic materials with controllable sensitivities. An improvement in energy density is obtained through linkage of energetic organic salts to transition metals, which breaks the ionic network of the salt and allows for more energy release upon combustion. Thermal sensitivity modulation is achieved by use of a magnetic field to stabilize a hexanuclear manganese cluster and increase its initiation temperature by 10.4 ± 3.9 °C. Furthermore, nitrotetrazole ligands were used to synthesize novel energetic coordination polymers with good oxygen balance. These complexes were studied with magnetometry experiments to probe the use of these materials as magnetically switchable explosives. Lastly, methylammonium salts were investigated for use as bridging ligands to create high-energy density clusters.
