Research Abstract

Guest molecule encapsulation to an isolated nano-cavity and analysis of dynamic behavior of the guest molecule responded to external stimuli on hybrid supramolecular capsule constructed from hydrogen bonds and metal-ligand coordination bonds were investigated. A cavitand molecule with coordination site and hydrogen bonding site self-assembled into a hybrid supramolecular capsule in the presence of divalent palladium complex. The hybrid supramolecular capsule can encapsulate neutral guest molecules and the structure was twisted at lower temperature. Guest exchange kinetics of a hybrid supramolecular capsule was strongly influenced by bidentate phosphine ligands of palladium complex.
