Résumé :	"A monograph which attempts to give the beginner or generalist some perspective on the field of crown ethers and cryptands and its early development. It also tries to give a notion of syntheses, binding phenomena, complex structures, and to offer a representative sample of applications."
Note de contenu :	"1 Introduction to macrocycle chemistry: crown ether precursor work-Pedersen's discovery of crown ethers- Simmons' in-out bicyclic amines- Lehn's cryptands- cram and carbanions- classes of crown ethers and cryptands-naturally occurring relatives of crown ethers- nomenclature and its problems-toxicity of crown ether compounds. 2 Syntheses of crowns, cryptands and their relatives: Pedersen's first crowns-- the ethylencoxy structural unit-- the template effect-- early syntheses of crowns-- syntheses of crown ethers-incorporation of aromatic subunits- nitrogen-containing macrocycles- crown ethers containing sulfur- syntheses of cryptands- spherands, cavitands, and carcerands. 3 Complexation by crowns and cryptands: the extraction technique-homogeneous cation binding constants- binding dynamics- cation transport- complexation of organic cations- anions. Part 4 Structural aspects of crowns, cryptands, and their complexes: uncomplexed crown and cryptand ligands- simple crown ether complexes of metal cations- complexes of cryptands- crown ether complexes of other ions and molecules- podand complexes. Part 5 Applications of crowns and cryptands: solubilization phenomena- cation deactivation- anion activation- phase transfer catalysis- sensors and switching- polymeric crown systems-membranes and channels- chirality, complexation and enzyme models-- receptor molecules-- miscellaneous applications and developments-the future of crown ether chemistry. 6 Additional reading: books crown ethers cryptands, and polyethers- monographs on phase transfer catalysis- reviews and articles."
