Framework Solids Laboratory
The main theme of research concerns the synthesis, structure and properties of new functional inorganic Framework materials.
New Frameworks and Mechanistic Studies
One of the themes of research being pursued at the Framework Solids Laboratory concerns the synthesis of new frameworks. In addition to the traditional framework builders such as phosphates, phosphites, arsenates, sulfites, oxalates etc, exploratory studies on thiosulfate and borates have been initiated. Another interest is to investigate the formation of open-frameworks from a fundamental perspective – (i) pathways, new mechanistic studies transformation studies etc.
Magnetism and Structure
Correlation of structure and magnetic behavior forms part of an important initiative of our research group. Canted antiferromagnetic, frustrated magnetic and related compounds have been prepared and their magnetic behavior has been modeled.
The metal-organic frameworks offer immense possibility for tailoring properties in a solid. The research initiatives in this direction have been to understand the role of temperature in the formation of a phase, mechanistic studies and to correlate the principles of coordination chemistry with the structure. Ligand exchange reactions, luminescence and magnetic studies on the prepared compounds indicate a wealth of properties in these solids.
