Preparation of Ionic Liquids-modified Metal Organic Frameworks Composite Materials and Their Application in Separation Analysis

Abstract Metal organic frameworks (MOFs) are a new type of porous materials with some unique characteristics such as uniform pore size, adjustable pore structure, easy synthesis and structural diversity. Ionic liquids-modified MOFs (ILs/MOFs) composite materials not only retain the structural characteristics of MOFs, but also have the advantages of adjustable physical and chemical properties of ILs with high stability. They have great application potential in the field of separation and analysis, which has aroused great interest of researchers. This article mainly reviews the preparation methods of ILs/MOFs composite materials and their research progress in separation and analysis in the latest five years, including adsorption/extraction, chromatographic separation, spectral and electrochemical analysis. And their future development trends are expected.
