| Summary: | Liquid-Liquid Extraction (LLE) is a venerable and widely used method for the separation of a targeted solute between two immiscible liquids. In recent years, this method has gained popularity in the supramolecular chemistry community due to the development of various types of synthetic receptors that effectively and selectively bind specific guests in an aqueous medium through different supramolecular interactions. This has eventually led to the development of state-of-the-art extraction technologies for the removal and purification of anions, cations, ion pairs, and small molecules from one liquid phase to another liquid phase, which is an industrially viable method. The focus of this perspective is to furnish a vivid picture of the current understanding of supramolecular interaction-based LLE chemistry. This will not only help to improve separation technology in the chemical, mining, nuclear waste treatment, and medicinal chemistry sectors but is also useful to address the purity issue of the extractable species, which is otherwise difficult. Thus, up-to-date knowledge on this subject will eventually provide opportunities to develop large-scale waste remediation processes and metallurgy applications that can address important real-life problems.
In this perspective we have summarized the current understanding of supramolecular interaction-based liquid-liquid extraction. |

| Bibliography: | Currently, he is a postdoctoral fellow at the Indian Association for the Cultivation of Science under the supervision of Prof. Pradyut Ghosh. His research interests include designing and executing chemical reactions for chalcogen bond based receptors for anion recognition as well as extraction. 2 − Pradyut studied at the Indian Institute of Technology Kanpur for a PhD with Parimal K. Bharadwaj and did his first postdoctoral work in the US at Texas A&M University with Richard M. Crooks during 1998-2000. He was an Alexander von Humboldt Fellow at the University of Bonn and Freie Universität Berlin in Fritz Vögtle's and Christoph Schalley's groups. Upon his return to India, he joined CSMCRI, Bhavnagar and in 2007 he moved to the Indian Association for the Cultivation of Science (IACS), Kolkata as an Associate Professor. In 2011 he was promoted to Professor of Chemistry and he was Head, Department of Inorganic Chemistry (2012-2015), Associate Dean (2015-2018) and Chair, School of Chemical Sciences (2018-2021) at IACS. Pradyut's present research interests are recognition, extraction and chemical sensing of ions of environmental and biological relevance, catalysis and interlocked molecules. S Sourav Pramanik received his Bachelor's and Master's degrees in chemistry from Vidyasagar University, Midnapore, West Bengal. Thereafter, he joined the Indian Association for the Cultivation of Science as a Research Scholar in 2020 under the supervision of Prof. Pradyut Ghosh. He is currently working on anion chemistry, in particular, anion recognition and separation following various supramolecular interactions. Dr Abu S. M. Islam received his M.Sc. in inorganic chemistry from the Department of Chemistry, West Bengal State University, India. Later he obtained his PhD from Jadavpur University, under the supervision of Prof. Mahammad Ali in 2019. During his PhD, he worked on detection and bio-imaging for small biomolecules like nitric oxide (NO), HSNO SH Iti Ghosh completed her B.Sc. in chemistry from Bethune College under the University of Calcutta. In 2022, she obtained her M.Sc. degree in chemistry from the Indian Association for the Cultivation of Science and in the same year she started her research career under the guidance of Prof. Pradyut Ghosh, working on anion recognition and separation by halogen and chalcogen bond-based receptors. nitrosothiol), and thiols (S ObjectType-Article-1 SourceType-Scholarly Journals-1 ObjectType-Feature-2 content type line 14 ObjectType-Review-3 content type line 23 |
