Talk Title : "Coordination Polymer Liquids and Glasses: Fundamentals and Applications"
Abstract
The field of coordination polymers (CPs) has to date focused on the crystalline state. More than 60,000 crystalline metal-ligand structures, formed from highly ordered arrays of metal nodes connected by organic ligands in at least one dimension, have been identified. However, interest in non-crystalline systems is growing, with amorphous solids, glasses and liquids identified as possessing similar metal–ligand bonding motifs to their crystalline cousins.1 In this presentations I will present new families of CP materials, called CP-glasses and CP-liquids. CP glasses are chemically and structurally distinct from the three other existing categories of glasses (inorganic non-metallic, organic, and metallic), and retain metal–ligand connectivity of their parent crystalline frameworks. Various routes for the realization of coordination glasses, structural designs, properties and applications in the area of clean energy will be discussed.2 A very first example of “Coordination Star Polymer (CSP) glass” developed in our group will be introduced. Finally, I will provide a perspective on the future of the non-crystalline domain of coordination polymers.
