Abstract
Although, the explosive materials are crucial for homeland safety and defense systems, they impose severe side effects on the environment and human health. The residues or byproducts of these hazardous materials can contaminate the environment and implies acute chronic effects on humans as well as animals. Hence, the ultrasensitive, low cost and convenient detection of widely used explosive compounds is highly desirable considering environmental pollution and increasing human health issues. Owing to their numerous features, luminescent metal-organic frameworks (L-MOFs) have gained much attention during the past few decades in the field of sensing with focus on national security, environmental monitoring, and forensic science. In this review, we have systematically described the detection of six kinds of widely used hazardous explosive compounds (nitroaromatics, nitramines, nitroalkanes, nitrate esters, peroxides and acid salts) using luminescent MOFs as the primary sensing material. The origin of fluorescence in MOFs, factors affecting the fluorescence, synthetic methods as well as various sensing mechanisms involved during the detection are discussed. Besides, most of the MOF based fluorescent probes reported in past decade for the detection of various explosive chemicals through diverse coordination interactions are summarized in tabular forms. Finally, the existing challenges and future prospects in the relevant research area are also discussed.
期刊介绍:
Sustainable Materials and Technologies (SM&T), an international, cross-disciplinary, fully open access journal published by Elsevier, focuses on original full-length research articles and reviews. It covers applied or fundamental science of nano-, micro-, meso-, and macro-scale aspects of materials and technologies for sustainable development. SM&T gives special attention to contributions that bridge the knowledge gap between materials and system designs.
