Design and synthesis of multitasking functionalized metal-organic frameworks

Abstract

The Investigations embodied in thesis entitled “DESIGN AND SYNTHESIS OF MULTITASKING FUNCTIONALIZED METAL ORGANIC FRAMEWORKS” was initiated in July 2015 in the Discipline of Chemistry, Indian Institute of Technology Indore. The objectives of this thesis are to investigate the perspectives of developing new Functionalized Metal-Organic Frameworks (FMOFs) based on specific functional groups for the achievement of desired properties and significant results. The focal points of thesis work are as follow-  Synthesis of a Lactam-functionalized porous MOF and exploring its catalytic activity for the chemical fixation of CO2 to cyclic carbonates in an economically viable way.  Utilization of the prepared Cu-MOF with graphene oxide nanosheets as an efficient adsorbent for the removal of MB dye in aqueous systems and a selective electrochemical sensor.  Synthesis of a novel amino-functionalized MOF having layered porous channels and exploration of its energy storage applications by preparing the hybrid through the incorporation of CNTs.  Exploration of solid-state structural reactivity with the phenomenon of Single-Crystal-to-Single-Crystal transformations in new Triazole-functionalized MOFs, obtaining novel topology.  Preparation of a new imidazole derivative based ligand as a fluorescent receptor for sensing of metal ions and bio-imaging. This thesis contains seven chapters and it begins with a general introduction emphasizing on the designing of MOFs constituted of various organic functional groups for the achievement of best possible performances (Chapter 1), followed by synthesis, structural description and applications of various functionalized metal-organic frameworks, along with the synthesis a new imidazole based fluorescent chemosensor for the sensing of metal ions and presenting biologically active properties in subsequent chapters. Finally, the thesis concludes with views on the prospects of optimizing materials for sustainable and cost-effective potential applications of the synthesized materials.
