Abstract:

In 1987, D J Cram, J M Lehn and C J Pedersen were awarded Nobel Prize in Chemistry �??for their development and use of molecules with structure specific interactions of high selectivity�?� and coined the term Supramolecular Chemistry. Jean Marie Lehn further linked supramolecular chemistry to adaptive chemistry due to lability/reversibility of noncovalent interactions which enable constitutional variations and the transition from design to selection through exchange, uptake and release of the molecular components of supramolecular entity. Supramolecular chemistry has been invaluable in elucidating some of the principles underlying the structure and function of the membranes. Molecular recognition is the biochemical basis of supramolecular chemistry and results in selective binding. The separation and selection of species from chemical or biological molecular pool is dependent upon its selective interaction with molecular receptors. Design and synthesis of molecular receptors/ionophores/ enzymes/synthetic transporters for specific purpose is the revolutionary concept in advanced day membrane technology. When chemical reactions are coupled with membrane permeation many interesting phenomena can occur. If reactions are carried out inside the membrane,the membrane acts as more than a partition and these membranes are called reactive membranes with increased flux - a revolution in unit operation and reactive membrane engineering. Liquid Membrane systems transport various substrates as cations/anions/amino acids/neutral species/ drugs from one phase to another facilitated by designed ionophores/receptors. Reactive membranes can be prepared by loading a selected membrane support with specially designed selective carriers/enzymes/membrane mimetic agents/natural and synthetic receptors. Reactivity control in membrane separation has been expected exponential growth in analytical, environmental and biomedical applications.
