Molecular self-assembly is an area of research that has spectacularly grown during the last two decades. The design of macromolecules that can adopt specific shapes and can act as receptors or host other molecules through non-covalent interactions has attracted particular attention.
One of the most popular building blocks in self assembly is calixarenes. However, although calix-[4]-arenes have been widely studied in the field of molecular recognition, calix-[6]-arenes have not received as much attention due to the flexibility of their skeleton. The design of calix-[6]-arenes is still a challenging task.
In this paper, Stephane Le Gac, Ivan Jabin and co-workers take advantage of the versatility of the calix[6]arene functionalization together with the flexibility of its skeleton to create additional host-guest and host-host interactions. The resulting supramolecular receptors are unique since these additional interactions are reminiscent of intra-protein interactions in biological receptors.
