Multi-topic Carboxylates as Versatile Building Blocks for the Design and Synthesis of Multifunctional MOFs Based on Alkaline Earth, Main Group and Transition Metals

ABSTRACT

Metal Organic Frameworks (MOFs), built from metal ions/clusters coordinated by organic linkers/bridging ligands, have emerged as an extensive class of crystalline hybrid materials with exceptional ultrahigh porosity and enormous internal surface areas. Out of several hallmarks possessed by MOFs, one is their topologically diverse and aesthetically pleasing framework structures which can be adjusted and tuned with the state-of-art techniques, and molecular simulations, different geometry, and connectivity of a linker to the respective metal cluster. In this critical review, we intend to highlight the scope of carboxylate-based MOFs by providing a varied range from their topology analysis and molecular simulations to different synthetic routes. Moreover, providing insights to reticular chemistry of carboxylate MOFs and the importance of Post-Synthetic Modification (PSM), an alternative route to introduce functional groups within these MOFs. We have also tried to identify the possible loopholes that can provide an extensive opportunity to young researchers that can lead to a detailed exploration in the field of novel MOFs.
