The main interest of our ongoing research is to synthesize metal-oxide based inorganic compounds and to exploit their host guest, ion exchange and catalytic properties. 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.

Recently we 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.
