The index n describes the number of repeating units of calix[n]arenes. Recently various means have been used, by which not only calix[4] arenes, but also calix[6]arenes and calix[8]arenes were synthesized [43]. Much attention has been focused to calixarenes of type II, because of their conformational flexibility and the possibility of obtaining different chemical modifications. In the case of calix[n] arenes, the different relative orientations of phenyl and hydroxyl... 

Calixarenes are the most easily derivatized of the common supramolecular host systems, and tens of thousands of calixarene derivatives have been synthesized. In order to focus this discussion. Sect. 23.2 of this chapter will present selected examples of calixarenes binding to amino acids, peptides, and proteins, with some examples that provide general lessons in calixarene chemistry and biomolec-ular recognition. A Table that serves as an index for all reported equilibrium constants, including solution conditions, is presented at the end of Sect. 23.2. Section 23.3 of the Chapter will report on recent efforts to use calixarenes in both host-guest and scaffold modes as the basis for new biomolecular technologies.
