Document from the year 2012 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, Gurukula Kangri University, language: English, abstract: Supra-molecular chemistry is one of the most popular areas of experimental chemistry because of the presence of a number of supra-molecular assemblies in nature. SURFACTANTS and CROWN ETHERS, representing the Colloidal systems and Macrocycles respectively, are the two significant parts of supra-molecular chemistry. The present work is based on the aim to study the crown ether- surfactant interactions.
