15.00
Unit I: 
Supramolecular Chemistry-I

Definition and development of supra molecular chemistry, nature of supramolecular interactions (ion pairing, ion-dipole, dipole-dipole, dipole-induced dipole and ion-induced dipole, van der Waals or Dispersion, hydrogen bonding, cation-π, anion-π,  closed shell, π-π stacking).

Classification of host-guest compounds, pre-organisation and complementarity: thermodynamic and kinetic effects.

Cation Binding: Complexation by crown ether, cryptands (spherical and tetrahedral recognition), spherands, lariat ethers and podands. Recognition of ammonium ions.Synthesis: Template effect and high dilution. Biological significance: Valinomycin and nonactin.

Anion Binding: Basic concepts of anion binding,cyclophanes and guanidinium-based receptors,neutral receptors: zwitterions, amide-based receptors. Biological significance: Phosphate and sulphate binding properties. Binding and recognition of neutral molecules.
