Explosives in the Cage: Metal–Organic Frameworks for High-Energy Materials Sensing and Desensitization

An overview of the current status of coordination polymers and metal–organic frameworks (MOFs) pertaining to the field of energetic materials is provided. The explosive applications of MOFs are discussed from two aspects: one for detection of explosives, and the other for explosive desensitization. By virtue of their adjustable pore/cage sizes, high surface area, tunable functional sites, and rich host–guest chemistry, MOFs have emerged as promising candidates for both explosive sensing and desensitization. The challenges and perspectives in these two areas are thoroughly discussed, and the processing methods for practical applications are also discussed briefly.

Metal–organic frameworks (MOFs) are promising candidates for explosive sensing and desensitization due to their atomically designable and predicable structure, permanent porosity, controllable host–guest interactions, tunable inner-surface environment, and diversity of organic/metal building units. The recent developments, challenges, and perspectives in the strategies for explosive sensing and desensitization by MOFs are comprehensively discussed.
