Prof. Mandal’s group is engaged in developing diversified chemistry of elements across the periodic table through a variety of interdisciplinary projects that involve (a) multi-step organic synthesis, (b) Schlenk-line and glove box techniques, (c) room temperature, hydro-/solvothermal and microwave synthesis of inorganic and metal-organic frameworks, and (d) high temperature solid state calcination of such frameworks. Various spectroscopic methods (UV-vis, FTIR, NMR, Raman, CD and Fluorescence), thermal analysis (TGA and DSC), microscopic techniques (SEM, TEM, AFM, Fluorescence and Confocal), electrochemistry, gas and vapour sorption measurements, X-ray crystallography (PXRD and SCXRD), and magnetic studies are routinely used for establishing physicochemical properties of the new organic, inorganic and organometallic compounds. The experimental work is aided by in-depth computational (DFT and GCMC) studies.
This has resulted in the strategic design of coordination architectures with a special emphasis on nanoporous materials including 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 decoding and separation, luminescence, gas and liquid adsorption, magnetism, etc. Our research efforts target alternate solutions to some current issues in the fields of (i) mesh-adjustable molecular sieves and adsorbent coolant (green air-conditioning), (ii) selective gas adsorption studies - storage of hydrogen and methane (next generation fuels), (iii) sequestration and conversion of carbon dioxide (lowering greenhouse effect), (iv) chormogenic and/or fluorogenic sensing of cations, anions and neutral small molecules at the ppm or ppb level, (v) chiral catalysis, and (vi) generation and applications of metal oxides and sulfides in luminescence, photocatalysis and quantum dots.
The research projects mentioned above are highly interdisciplinary involving people interested in materials science, organic synthesis, coordination chemistry, catalysis, and organometallic chemistry.
