Advance in Applications of Metal-organic Gel

Key Words:

Abstract:Metal-organic gels (MOGs) are a kind of gel material formed by bridging metal ions and organic ligands via non covalent interactions. In comparison with metal-organic frameworks (MOFs) that require time- consuming preparation, MOGs can be obtained by self-assembling through the coordination under mild conditions to form porous supramolecular structure via hydrogen bonding interactions, pi-pi stacking and van der Waals forces. MOGs possess good surface accessibility, high surface area, and multiple stimuli-responsive properties. Due to the easy preparation and large specific surface area, tunable structure, and abundant metal sites, MOGs are widely used in the fields of sensing and analysis, and also show unique advantages in the fields of catalysis, adsorption, energy storage and electrochromic devices. In this paper, the research and application progress of MOGs in the above fields in recent years is reviewed, and the challenges, future trends and application prospects are discussed.
