Providing a comprehensive state-of-the-art account, this volume is exclusively devoted to the analytical chemistry of Macrocyclic (crown ethers), macrobicyclic (cryptands) and the supramolecular compounds (calixarene and calyx(n) resocrinereme and Rotaxanes). These compounds having a great deal of similarity in their chemical characteristics and have direct application in biosciences, analytical chemistry and many other subjects. The book offers an insight into chromogenic crown ethers in solvent extraction describing the classification, synthesis and applications in extractive photometry.
