Synthesis of metal-organic frameworks for energetic applications

Despite the fact that MOFs have been investigated in several application fields, the use of MOFs as energetic materials has not been fully explored yet. MOFs can be potential energetic materials because of their high densities and high heats of detonation. Additionally, they are expected to present some advantages compared to well established macromolecules such as organic polymers. Indeed, several reported MOFs have revealed their great potential as more stable new-generation high explosives. A simple strategy for the synthesis of energetic MOFs consists of partially exchanging the ions within the framework with energetic ions. Herein, we present the results of a systematic study on the preparation of such materials. Three different metals (Zn, Co and Ni) were combined with 1,4-Di(4'-pyrazolyl)benzene (BDP), the metal was first exchanged with K+ and subsequently with Guanidinium Nitrate (GUNI) and Guanylurea Dinitramide (FOX-12).
