4,4′-Azobis(1,2,4-triazole): A Versatile Molecular Scaffold to Develop Tailor-Made Energetic Materials

Abstract

Energetic materials containing azoles are appealing in terms of their high nitrogen content and presence of functional groups that can participate in different non-covalent bonding interactions. One such interesting compound is 4,4′-azobis(1,2,4-triazole) (ATRZ), which has formidable energetic parameters. Based on the presence of hydrogen-bond acceptor and metal coordination sites, a number of tailor-made energetic materials have been derived by employing ATRZ as the molecular precursor. In this review, we discuss the use of this high-energy molecular scaffold in the development of different energetic cocrystals, coordination polymers, and composites and discuss their properties in the context of state-of-the-art energetic materials.
