Seminar: A/Prof Krishna K Damodaran - Assembling Multi-Functional Organic Ligands to Smart Materials

Speaker: A/Prof Krishna K Damodaran

Supramolecular chemistry, defined as “chemistry beyond the molecule” has an important role in designing and implementing functional chemical/natural systems based on molecular components, which are assembled via non-covalent interactions. The 50th anniversary of supramolecular chemistry was celebrated this year, which was introduced by Charles Pedersen’s in 1967 with his landmark work on crown ethers. Self-assembling supramolecular materials can be achieved at any scale, ranging from the nano- and micrometer scale to macroscopic dimensions. We are interested in developing smart supramolecular systems using multi-functional organic ligands capable of inducing non-covalent interactions such as such as hydrogen bonding, halogen bonding, van der Waals interactions, π−π stacking etc. The hierarchical assembly of the functional ligands in presence of external stimuli (anions, metal ions, heat, light etc.) resulted in smart materials, namely metal-organic complexes/polymers and supramolecular gels. The application of these materials in gel phase crystallisation and CO2 conversion will be discussed.
