Abstract |
Metal-organic frameworks based on metal-oxo chain clusters for their environmental applications
For last two decades, metal-organic frameworks (MOFs) as the newly emerging porous materials have attracted tremendous research attention owing to their potential applications such as in gas storage/separation, catalysis, sensing, and so on. Unlike the traditional porous materials, MOFs are built by coordination bonds between organic ligands and metal ions/clusters. Thus, it leads to the designability and tailerability of their structures and properties through the judicious choice of organic linkers and metal ions/metal clusters. Herein, first, the Ti(IV)-carboxylate MOF with an unprecedented Ti-oxo chain cluster will be presented by focusing on their structures and photocatalytic activities. In the second part of the talk, iodine sorption properties such as kinetics and thermal stabilities of two isostructural MOFs consisting of metal-oxo chain clusters will be discussed. The slight structural difference in the ligands resulted in significant difference in the iodine sorption behavior. Single crystal X-ray diffraction analysis clearly determined the location of the iodine or triiodo-molecules in the two MOFs.
