Luminescent Metal-Organic Frameworks for Nitroaromatic Compounds Detection

Luminescent metal-organic frameworks (LMOFs), as a subclass of MOFs, have attracted great attention, due to their promising potentials in practical applications. Therefore, as chemosensors, by combining the characteristic luminescent properties and the diversiform topological structures, LMOFs open up promising potentials for sensing. Nitroaromatic compounds (NACs) pose a great threat for environment and homeland security because of their toxicity and explosiveness, and then developing sensitive, selective, and reversible sensors for NACs is in great demand. In this review, we summarize recent works on LMOFs sensors for NACs through photophysical properties, sensing behaviors, possible mechanisms, existing problems and prospects for further developments.
