Study reveals acceptor properties of amide resorcinarenes toward metal cations, highlighting their use under heterogeneous conditions.
By exhaustive functionalization of -tetra--phenethylresorcincalix[4]arene, new modified derivatives containing 8 terminal amide fragments and differing in components and size of spacers connecting the macrocyclic core with them, as well as the nature of amide groups, were synthesized. Using UV spectroscopy, acceptor properties of amide resorcinarenes towards metal cations under heterogeneous and homogeneous conditions were studied. The effect of macrocyclic core preorganization of ligand on its ability to form complex with metal cations was demonstrated.
