Metal-organic framework materials (MOFs) are porous materials with a crystal structure formed by self-assembly of secondary or structural units of metal ions or metal ions, and organic ligands containing nitrogen and carboxylic acid functional groups, and metal organic framework materials. They have a very high specific surface area and a very high porosity, and their pore structure is adjustable compared to conventional porous materials. The luminescence mechanism of metal-organic framework materials includes: based on central metal ion luminescence, based on organic ligand luminescence, ligand-to-metal charge transfer (LMCT) or metal-to-ligand charge transfer (MLCT) luminescence, based on package which has guest molecule with excellent luminescence performance emits light. The detection of the analyte by changing the fluorescence spectrum of the metal organic framework material by the analyte, the metal organic framework material fluorescent probe has been widely used in many fields. Fluorescent probes for metal-organic framework materials mainly include fluorescent probes of classical metal-organic framework materials, fluo-rescent probes of metal-organic framework materials modified by post-synthesis modification, and fluorescent probes of composite metal-organic framework materials modified by encapsulation of guest. In the past, researchers have been mainly concentrated on the preparation of fluorescent probes for classical metal-organic framework materials. Recently, in order to enrich the types of detectable targets, they have begun to study the advantages of adjusting the pore structure of classical metal-organic framework fluorescent probes and superior fluorescence performance. The guest materials are combined to develop a composite metal organic framework material fluorescent probe or a classical metal organic framework material fluorescent probe for post-synthesis modification, thereby enhancing the fluorescence performance and specific sensing performance of the classical metal organic framework material fluorescent probe. In this paper, the application of fluorescent probes of metal-organic framework materials in the detection and identification of explosives, anions and cations, bio-small molecules, temperature, pH and water waiting for analytes in recent years is introduced. The design concept of fluorescent probes for metal organic framework materials is summarized, which provides a new idea for the design and development of fluorescent probes for metal organic framework materials. © 2020, Materials Review Magazine.
