ABOUT THE MOF
In the last decade, metal-organic frameworks (MOFs) containing light and environmentally benign metals have attracted researchers from industry and academia since they are believed to be well suited for applications especially in the field of gas storage. Compared with zeolites, an exceptional degree of design tunability can be achieved in MOFs by judicious selection of inorganic and organic components, or via post-synthetic modifications. The possibilities of using MOFs have been realized in most applications where zeolites have been employed; however, major progress is achieved only on gas storage and separation applications. Owing to their favorable properties the synthesis of some of the Al-MOFs has been scaled to a multi-kilogram scale, reported examples are Al-MIL-53 (Basolite A100) and an aluminum fumarate (Basolite A520).2 Al-MIL-53 is also the most intensively and best studied Al-MOF since it (i) can be readily synthesized in water, (ii) can be modified with different functional groups by direct synthesis and post-synthetic modification (PSM), (iii) is chemically and thermally stable, (iv) exhibits a strong framework flexibility, and (v) was the first Al-MOF that was available in larger quantities.
Accordingly many gas and liquid sorption and with growing industrial resources, Aluminum is one element of choice for the synthesis of such MOFs since it leads to stable and highly porous materials that can also be formed in water as a green solvent. The potential application of the Al-based MOFs is well documented in various patents mainly issued by the pioneers of this field-BASF and the groups of Ferey and Loiseau and press releases have been issued announcing large scale testing and their solvent-free synthesis At a molecular level, simulation can provide microscopic insights from the bottom-up and establish structure-function relationships. In this thesis, the objectives are to investigate heterogeneous catalysis, ethanol/water separation and functionalization in chemically and thermally stable MOFs.
ABOUT THE CONFERENCE AND THRUST AREAS
Justification of the research team “Supramolecular Chemistry and Functional Materials towards the thrust area “Energy”
All the functional materials proposed from our research team focuses towards the thrust area of “Energy” including the development of thermoelectric materials, DSSCs, artificial photosynthesis, green synthesis, chiral catalysis, gas storage and separation, energy storage and conversion and optoelectronics.
The organic, inorganic and hybrid materials proposed have applications in the field of catalysis and optoelectronics. The functionalised mesoporous materials can be used in catalysis, host guest chemistry and in energy conversions.
Metal organic frame works (MOFs) are of cheap cost, easily available, can be synthesized environmentally friendly, are of high stability, with low toxicity, and can be synthesized in a greener way without pollution. The applications of MOFs include gas storage and separation, catalysis and sensing.
Photo and electro-catalysis using transition metal complexes includes the use of light energy and electricity as source of energy. These catalysts have high stability under homogeneous condition. They possess high selectivity and reactivity. They are applied in direct reduction of small organic molecules like CO2, carbonyl compounds without use of H2 gas.
The applications of Photo and electro-catalysis using transition metal complexes include reduction of variety of electrophilic organic compounds like CO2, organic carbonyl and imine compounds. Artificial photosynthesis by fixation of CO2 to energy rich chemicals like formic acid, formaldehyde, methanol, cyclic carbonate, carboxylic acids and asymmetric catalysis.
In the research area main group organometallic chemistry with special emphasis on Boron, Silicon, Antimony and Bismuth based π conjugated materials, electronic conjugation between main group element and neighbouring aromatic units can produce highly luminescent pigments with potential applications in various fields such as bio-probes, solid state lightening, forensic materials and solar cells. Additionally, the Lewis acidic properties of these materials can be exploited for hazard detection.
Thus “Supramolecular Chemistry and Functional Materials research team is multidisciplinary research team will work towards the thrust area of “Energy”.
