| dc.description.abstract | Metal-organic frameworks (MOFs) are a new class of highly porous coordination polymers. They are interconnected by the inorganic building units and organic linkers in a 2D or 3D fashion. MOFs have emerged as a new class of highly crystalline materials over other traditional porous materials such as zeolites, silicas, activated carbons, etc. MOFs have large surface areas and permanent porosity. Extending the length of organic linkers leads to increase in pore sizes for the resulting MOFs. Attaching hydrophobic functional groups with the organic linkers enhances hydrophobicity of the MOFs. The tuneable functionality and precise arrangement of the organic linkers make them potential candidates for selective gas adsorption, separation, chemical sensing, proton conductivity, electrical conductivity, heterogeneous catalysis, photo-catalysis, drug delivery, etc. The MOF-based fluorescence sensing results from the incorporation fluorescent linkers or incorporation of f-block metal ions. Post-synthetic modification of MOFs also enhances some additional properties in chemical sensing, drug delivery, gas sensing, chemical stability, etc. Due to the formation of strong bonds between metal ions (specially in high oxidation states) and carboxylate groups of organic linkers, the resulting MOF materials show high thermal and chemical stability, which are desirable for practical applications such as gas adsorption and chemical sensing. Inspired by the above-mentioned advantages, a broad variety of MOF materials have been investigated for gas storage as well sensing of a wide range of analytes including cations, anions, biomolecules, small molecules, volatile organic compounds and nitro explosive materials | en_US |
