Metal-organic frameworks (MOFs) have significant structural advantages and are applicable in various fields. They can encapsulate a variety of luminescent guest species, giving them a broader luminescent capability. This review systematically introduces the applications of various LG@MOF sensors in fluorescence detection of ions, biomarkers, pesticides, and preservatives, as well as the development of portable visual fluorescence sensing applications. The challenges and potential for future growth in these sectors are also briefly discussed.
Metal-organic frameworks (MOFs) have excellent applicability in several fields and have significant structural advantages, due to their open pore structure, high porosity, large specific surface area, and easily modifiable and functionalized porous surface. In addition, a variety of luminescent guest (LG) species can be encapsulated in the pores of MOFs, giving MOFs a broader luminescent capability. The applications of a variety of LG@MOF sensors, constructed by doping MOFs with LGs such as lanthanide ions, carbon quantum dots, luminescent complexes, organic dyes, and metal nanoclusters, for fluorescence detection of various target analyses such as ions, biomarkers, pesticides, and preservatives are systematically introduced in this review. The development of these sensors for portable visual fluorescence sensing applications is then covered. Finally, the challenges that these sectors currently face, as well as the potential for future growth, are briefly discussed.
