• interactions that can occur in ion binding [8] and capsule formation [34]. Likewise, introduction of hydrogen bonding groups like those of 9 are crucial for achieving interactions with various substrates [35][36]. Coupling an aromatic ring onto the upper-rim of the fluorous calixarene led to an increase in
