Recent advances in carboxylate-based indium(iii)–organic frameworks

Indium-based metal–organic frameworks (In-MOFs) are gaining popularity as a research topic because of their distinct structural and practical advantages. Researchers understand that the indium atom has a comparatively big radius and is ecologically benign. Importantly, the In(III) cation has a distinct electronic configuration with a high cyclic p-block, and establishes strong coordination bonds with atoms such as O, N, and S in various Lewis acid environments. As a result, the stable In-MOFs with varied structural kinds and chemical properties deserve thorough exploration. The research progress must be properly evaluated to understand the future research trend of In-MOFs better. Furthermore, this analysis of In-MOFs will close gaps in the current literature, and a full assessment of such MOFs will immensely benefit future research. It should be noted that we are primarily interested in MOFs built using carboxylic acid ligands. Herein, we will discuss the preparation methodologies, structural features, and diverse applications of MOFs made up of indium(III) nodes and various linkages, as well as current and prospects.
