Our research projects include the synthesis and characterization of open framework transition metal structures and large metal-containing supramolecular assemblies that have potential for guest uptake (gas storage, molecular sensing), the study of selectivity in organic host-guest systems, and the beneficiation of pharmaceutically relevant materials through the investigation of their polymorphs, solvates, cyclodextrin inclusion complexes and co-crystals. Solid phases are studied using powder and single crystal X-ray diffraction, thermal analysis (including TGA and DSC) and spectroscopy (FT-IR and solid-state NMR techniques). The thermodynamics of inclusion and complexation processes in solution are investigated by high-resolution spectroscopy and isothermal titration calorimetry.

Curriculum Vitae
Research Interest
I, Dr. Rajdip Dey, would like to set down the focus of my research interest and career endeavors, and to justify my chosen areas of specialization with reference to my background and experience. I got hooked onto chemistry so much that I decided to embark on a scientific quest and take up chemistry as a main subject in higher studies. When I was in 11th standard, for the first time, I got the taste of Chemistry as my main subject. From that very time, each and every phenomenon in chemistry aroused a sense of curiosity within me. Gradually I realized chemistry is not confined to the shackles of just few textbooks, but it is diffused to our everyday living. During my doctoral research work, I have done several syntheses of metal-organic hybrid materials and successfully characterized those using different analytical techniques. Already, I have bagged more than 15 publications in the reputed scientific international refereed journals and a number of manuscripts has also been communicated or under preparations. Currently, I am engaged in the research on the synthesis of functional coordination polymer (1D/2D/3D) by exploiting the dicarboxylate (malonate/succinate/glutarate etc) or monodented N, N donor (pyridine and its derivative) as coligand. Some neutral bridging ligands (4,4′ bipyridine, pyrazine etc) are also used in combination with dicarboxylate acid salt, pseudo halogens in different metal system (Cu(II),Ni(II),Mn(II),Co(II), Cd(II),Zn(II) etc.). I have synthesized a number of novel 1D, 2D and 3D coordination or supramolecular architecture of metal using different organic and inorganic spacers. It is the bridging organic ligands that allow the large diversity in the topologies and possible properties of the metal-organic coordination networks. Sometimes these coordination polymers are self assembled from metal ions or cluster that are linked to each metal by organic linking molecules to generate infinite framework structure. The effect of weak interaction on the crystal packing of such complexes is the central theme of my research interest. In summary, currently I have a sound experience in designing and synthesizing coordination polymer.
