Our research aims to design and synthesize several functional materials by the utilization of crystal engineering approaches.  The judicious choice of hydrogen bonds, several other intermolecular interactions and coordination bonds are the key for the creation of novel materials with predefined structure and therefore desired properties. The extended framework structures via coordination and covalent bonds results in MOFs & COFs, respectively, with high porosity, selective adsorptivity, dye encapsulation and catalysis.  Also these materials exhibit excellent ability for post synthetic modifications to produce the materials otherwise can’t be synthesized and they display novel properties which are very different from those of the parent materials.  The hydrogen bonding or supramolecular synthon assisted cocrystals, organic salts and metal assisted organogels were also of our interest for their multifunctional properties which include SCSC [2+2] dimerization/polymerization reactions, luminescence and proton conductivity. Furthermore, synthesis of SOFs with intriguing photocatalytic properties for water splitting also is part of our research interests.
