Our Research

We are mostly interested in functional inorganic materials that are vital to create innovative science and technology and thereby to address the issues of sustainable energy, healthcare and a clean environment.

(1) Functional inorganic materials based on polyoxometalates (POMs), basic metal carboxylates (trinuclear metal oxo clusters), metal organic frameworks (MOFs) and metal-dithiolene coordination complexes.

(2) The molecular functions include sensing toxic substances / molecular recognition (referring health care), electrocatalytic water oxidation to oxygen, electrocatalytic water reduction to hydrogen (referring sustainable energy), aerial CO2 fixation (environmental care) and its use in organic synthesis, solid state proton conduction and electrocatalyic oxygen reduction (in the context of fuel cell, energy issue). The synthesized materials also exhibit chiral separation, electrocatalytic proton reduction to molecular hydrogen, reversible syn-anti isomerization in the solid state (molecular machine) and organic functionalization (of industrial importance).

(3) Exploring the solid-state properties of hybrid materials prepared by functionalization of inorganic complexes with different organic moieties. Developing new class of dithiolene materials exhibiting near IR absorption,conducting and NLO properties. Crystalline state transformations focusing gas-solid, gas-liquid reactions and light induced conversions. Another area, we are involved, is to study the supramolcular aspects of the molecular assemblies built from different organic and inorganic precursors.

(4) we are also involved in the crystal engineering of Metal-Organic Frameworks in terms of design, synthesis, self-assembly and exploring the functional potential applications in the fields of adsorption, magnetic properties etc.
