    • To the best of our knowledge, the role played by rigidity of calixarene receptors on their complexation efficiencies in apolar solvents has never been systematically studied. Only a few studies have been reported so far in the literature in which the efficiency vs. rigidity has been taken into account, see e.g. Ref. 5

    • 3). A tentative explanation of such behavior could derive from the possibility of the two ureido sidearms to mutually interact, hence decreasing their ability to cooperatively act as H-bond donor groups.
