Dr. Krishna´s research contribution to date have been within the area of Inorganic chemistry and material properties such as sorption studies, anion recognition etc. of coordination polymers, effect of anion binding on organic receptor molecules, inclusion properties of metalloporphyrins, catalysis and gel chemistry. Our group have been working on the development of low-molecular weight supramolecular gelators (LMWGs) and their structure property correlation. Our current research is based on the syntheses of gelators that match the chemical structure of the crystallization substrate and hence provide an active nucleation surface for organic/inorganic (drug) molecules. We have compared the gel phase and the solution state crystallization of Cu(II) complexes in various solvent compositions and showed that gel phase crystallization results in thermodynamically stable form under ambient conditions.The tuning of gelation ability (MGC) and thermal/mechanical strength of parent gelator by alerting the functional group have proved the importance of non-bonding interactions and functional groups in designing LMWGs with tunable properties. We have also shown the role of metal coordination in supramolecular gel formation by coordinating zinc(II) and cadmium(II) salts with pyridyl amide based non-gelator ligands. Our idea is to explore mechanochemistry in gel phase crystalistion and compare the morphology of the crystals
