Research Expertise

The expertise of Dr. Mondal:


          I have evolved with many expertise over one and half decades. I have developed the synthesis of metal complexes using organic ligand and their characterization when I did my two years of MS work with Prof. P. S. Mukherjee at IISc, Bangalore (2006-2008). (1) I have also worked as a summer trainee with Prof. S. Bhattacharya to learn organic synthesis and purification by TLC and column chromatography (Summer of 2005; IISC, Bangalore). (2) I also did a one-month project in the laboratory of Prof. T. N. Guru Rao at IISc, Bangalore to strengthen my X-ray structure refinement (winter of 2005). (3) During this period, I additionally learned X-ray single-crystal data refinements and analysis of magnetic data of first-row-transition metal complexes. (4) I learned much about the magnetism of bulk and molecular complexes during my Ph.D. Here I had to handle an X-ray single-crystal diffractometer, SQUID machine, heat capacity machine. Here majorly I have done the synthesis of over one hundred 3d, 3d-4f based coordination clusters of anisotropic paramagnetic and diamagnetic ions. All the complexes of paramagnetic and diamagnetic ions were isolated, characterized, and studied by magnetic and fluorescence measurements, respectively. I have gained the expertise of magnetism and fluorescence properties during my Ph.D. thesis work with prof. Annie K. Powell at KIT, Karlsruhe, Germany (2008-2011). (5) I moved to Goettingen, Germany to work with Prof. H. W. Roesky during which I learned completely different pieces of stuff for which Georg-August University, Goettingen is very famous. I learnedthe Schlenk line technique thoroughly to deal with extremely air and moisture sensitive stable singlet carbene ligand which I have employed as ligands for the synthesis of main group elements and first-row-transition metal complexes. Here we have encountered cyclic voltammetry of extremely sensitive air and moisture sensitive compounds/complexes, sampling for magnetic measurements, theoretical calculations (DFT, QTAIM, EDA-NOCV) which we are routinely doing on our own here in IIT Madras independently. We have customized all the leak-proof glass apparatus with a Chennai-based glass blowing company for which the allowed fund from ECR-DST was utilized.


          In addition, (6) we have gain expertise in the characterization of solid-state micro-, nano-materials of metal oxides by EDAX, SEM, TEM, powder XRD, MASS, NMR. (7) I have a customized air and moisture sensitive setup for mounting a single crystal at IIT Madras. We regularly use them with success. (8) I have purchased visible light and UV light chamber where photochemical reactions will be carried out. (9) I have a glove box work station (IIT M funded) to handle the air and moisture-sensitive materials under argon. (10) I have solvent purification apparatus and a machine (ECR-DST funded). (11) The lab is entirely air-conditioned which is suitable for sensitive chemistry at IIT Madras. (12) One Ph.D. student is thoroughly trained in EDA-NOCV calculation and analysis.
