Research Interests
The systematic development and synthesis of atomically engineered multifunctional molecular systems that can be controlled with the aid of external stimuli have garnered enormous interest within the realm of materials chemistry. This pursuit is inspired by the aspiration to achieve our futuristic technological and energy goals. As a research group specializing in inorganic molecular materials chemistry, we aim to leverage our expertise in coordination, supramolecular, and crystal engineering chemistry to meticulously design targeted molecular and polymeric systems. These systems with defined physio-chemical properties hold promise for potential technological implementations in the fields of high-density information storage, quantum information processing, multi-responsive magnetic materials, magneto-optical devices, light-responsive switches, and molecular magnetic coolants. Efforts are directed towards translating and fabricating these smart multifunctional systems to substantiate the prospective technological applications of these materials. We employ a diverse array of characterization techniques, including X-ray crystallography, infrared, UV-Vis, NMR, EPR, Mössbauer spectroscopy, mass spectrometry, TGA, cyclic voltammetry, and SQUID magnetometry, among other methods. Collaboration with theoreticians is undertaken to elucidate the underlying electronic structures. In addition, we are also interested in designing molecular systems to support transition metal complexes in unusual oxidation and spin states as catalysts for novel molecular transformations.
