Special Calixarenes, Synthesis and Propertiesmpounds in which all the .-butyl groups are removed and replaced by other functional groups. The construction of more sophisticated, special calixarenes which could serve for instance as enzyme models, requires new synthetic approaches capable of producing molecules with .

Calixarene-Based Cation Receptors and Carriersors and carriers showing improved efficiency and selectivity. For the complexation of spherical alkali and alkaline earth cations the most effective way to arrange the ligating sites is in the form of a macrocyclic structure, as in Pedersen’s .. Lehn’s .. and Cram’s .. .

Conformations of Calixarenes in the Crystalline State higher linear oligomers and finally by cyclisation, to the calixarenes. During these processes it has been suggested that intra- and intermolecular hydrogen bonds maintain the reacting intermediates in conformations and relative mutual arrangements favorable to the formation of the calixarenes (see Gutsche’s chapter, .).

Lanthanide Ions and Calixarenesthe crown ethers , cryptands and spherands perhaps signifies the most important recent development of the field. Certainly it is now possible to exert numerous subtle forms of control over the coordination of phenolic oxygen and consequently over the properties of the metal ion to which it is bound.
