Research Focus Prof. Mandal’s group is engaged in developing diversified chemistry of elements across the periodic table through a variety of interdisciplinary projects that involve multi-step organic synthesis, coordination chemistry, catalysis and materials science. Various spectroscopic techniques (UV-vis, FTIR, NMR, Raman, CD and Fluorescence), thermal analysis (TGA and DSC), electrochemistry, surface analysis (SEM/EDX, AFM and TEM), and X-ray crystallography (PXRD and SCXRD) are routinely used for establishing physicochemical properties of the new organic, inorganic and organometallic compounds. This has resulted in the strategic design of porous materials with a special emphasis on Metal Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) for their diverse structural aesthetics and for their possible roles in various applications, such as catalysis, molecular separation, luminescence, gas and liquid adsorption, magnetism, etc. The major projects that we have worked on are: (i) design of bifunctional heterogeneous catalysts with hydrogen-bond-donating (primary amide group) and/or hydrogen-bond-accepting (oxadiazole moiety) capabilities along with Lewis acid centers for a number of important organic transformations, and (ii) development of multifarious micro- and mesoporous nanomaterials for (a) sequestration and conversion of carbon dioxide, (b) ultrafast/selective sensing of metal ions and neutral small molecules (nitroaromatics and ketones) at ppb/ppt level, and (c) study of non-radioactive surrogates of nuclear wastes such as multimedia I2 capture and selective sensing of ReO4- in water, and (iii) generation and applications of metal oxides and sulfides in luminescence, photocatalysis, organic transformations, and adsorption of pollutants.
