From the greek 'calix
' meaning bowl, and the suffix
'arene' which usually means aromatic ring. Linked phenyl
c12cc(C(C)(C)(C))cc(c2O) C c3cc(C(C)(C)(C))cc(c3O)
C c4cc(C(C)(C)(C))cc(c4O) C c5cc(C(C)(C)(C))cc(c5O) C1
The linking methylene groups are separated to empahise the fourfold symmetry. The (C(C)(C)(C)) moeties are bulky t-butyl groups that form the 'rim' of the bowl, and are para- to the hydroxyls which form the base.
If the t-Bu are replaced with charged sulphate groups, and a corresponding calixarene with positively charged trimethyl amino groups is constructed - a complex can form. Think of two eggcups with velcro on thier rims (hooks on one and loops on the other) stacked to form a hollow cavity.
