the resorcin[4]arene cavitandsusing the ring closing metathesis reaction (RCM) in perallylated resorcin[4]arenes was investigated. The formation of resorcinarene cavitands offers unique molecular platforms for host–guest chemistries, sensor development, metal complexation, as well as new polymers and self-assembled systems, and as potential reaction sites, and novel catalytic platforms.

extended pi surfaces stabilize the dimer similar to velcrands, while eight hydrogen bonds act like snaps to hold the molecules together. The self-complementary array of hydrogen bonding sites were incorporated on the upper rim of a resorcinarene-based cavitand. A dramatic reorganization of shape and size of the internal cavity was manifested through changes in solvent polarity. Specifically, the equilibrium
