Trimeric and hexameric calixarene-based capsules

In this paper trimeric and hexameric capsules are presented. In the first section trimeric calixarene-based capsules are described, they are followed by trimeric cavitand-based capsules. In the second section hexameric resorcinarene-based capsules are characterized; moreover two examples of covalently bound hexameric cavitand-based capsules are shown.
