MOF-74 with high-density exposed metal sites, adjustable one-dimensional pores, and high thermal stability, has attracted extensive attention and in-depth exploration of scientific researchers. This review summarizes the development of MOF-74 from the following three parts: 1) mainly focusing on the structures and assembly strategies of MOF-74 and its isomers including solvothermal method, normal temperature method, microwave assisted method, Dry-Gel method, etc. In addition, the effects of reaction solvents, auxiliary ligands, regulators and other factors on the target compound are also discussed; 2) Considering the synergy effects among the materials, the development status of MOF-74-based composite materials is also summarized, including the construction types of materials and typical synthesis methods; 3) The special properties of MOF-74 such as porosity, Lewis acid-base sites, structural stability, and the excellent performance of the composite material are further discussed in detail, which allow the MOF-74 framework material to find wide applications in the fields of catalysis, separation, detection, adsorption, and energy storage. Finally, a reasonable idea for the construction of the new MOF-74 isomers has been discussed.
