Molecular Structure and Dynamics: Disruptive Energetic Materials: The Synthesis and Stabilization of High-Nitrogen compounds and Next-Generation Energetic Materials

Abstract

Energetic materials chemistry encompasses all of propellants, explosives and pyrotechnics; metastable compounds or mixtures capable of releasing stored energy. This nature of these materials results in one of the fundamental challenges of the field, the ability to produce a material capable of releasing large amounts of energy, yet being of sufficient stability for safe handling and only releasing stored energy when desired. Unfortunately, this issue become more pronounced when the extremes of energetic performance are sought; in many cases, the highest-performing energetic materials are also the most sensitive to mechanical, thermal, or electrical stimuli. Creation of energetic materials with record breaking performance while possessing insensitivity towards these types of stimuli is a major goal of the proposed research. On the molecular level, new insights are necessary to create methods of increasing energy content while retaining stability, especially as energetic materials are designed using all-nitrogen backbones such as pentazoles. In this work various thrusts for disruptive energetic materials are proposed. These thrusts include such work as the preparation of all-nitrogen heterocycles, methodology for the stabilization of high-N and all-N systems, and synthetic routes to functional groups that have the potential to be used in the creation of energetic materials of very high performance. This work will cover all steps from the development of new synthetic methods for high-N and all-N chemistry, work on model systems to demonstrate methods of stabilizing molecules with unprecedented nitrogen and energy content, the synthesis of functional energetics and the calculation and measurement of energetic properties of the prepared molecules.
