Recent advances in carboxylate-based indium(III)-organic frameworks

Because of their unique structural and practical benefits, indium-based metal-organic frameworks (In-MOFs) are becoming increasingly attractive as a study area. Everyone knows that the indium atom has a relatively large radius, and is environmentally friendly. Importantly, the In(III) cation has a unique electronic configuration with a high cyclic p-block, allowing it to form strong coordination bonds with atoms such as O, N, and S in the presence of a variety of Lewis acids. Therefore, the constituted stable In-MOFs with various structural types and chemical properties are worthy of systematic study. To better comprehend the future research trend of In-MOFs, it is necessary to evaluate their recent research progress thoroughly. Furthermore, this analysis of In-MOFs will fill gaps in the current literature, and we believe that a thorough review of such MOFs would be extremely valuable to future research. Note that we mainly review these MOFs since In-MOFs in the literature are mainly constructed by carboxylic acid ligands. In this review, we will conclude the preparation methodologies, structural peculiarities, and numerous uses of MOFs composed of indium(III) nodes and various connections, as well as present and future possibilities.
