    • Throughout this paper the trivial name cavitand will be used for the rigidified tetrameric resorcinarene framework of the adsorbates. The official IUPAC name is 7,11,15,28-tetrakis(XX)-1,21,23,25-tetra-(YY)-2,20:3,19-dimetheno-1H,21H,23H, 25H-bis[1,3]dioxacino(5,4i:5′,4′i′]-benzo[1,2d:5,4d′] bis[1,3]benzodioxocin, in which XX refers to the aromatic rings substituents and YY to the methylene bridge substituents.

    • Measurements with toluene were also carried out but did not g ive reliable signals for any of the adsorbate monolayers. The intensity o f the signals was high, suggesting strong interaction with the adsorbates, However, they contiuously changed and the layers showed results obtained with toluene are not reported in this paper.

    • The solutions were not buffered because, after some initial measurements carried out with aqueous solutions of guests, no dependence of the acidity of the solutions on the interactions with receptors 1-4 could be detected.

    • For the comparison of the results obtained on the receptor layer, other reference layers could have been used. Different types of reference layers, for example hydroxyl-terminated and perfluorinated alkanethiol monolayers, are currently being studied to try to determine in which case the interactions with the guests are minimal.

    • Concentretion dependence experiments were not carried out w ith adsorbates 2-4 because there was no reason to believe that these receptor layers would behave in a fundamentally different way from adsorbate 1.

    • At higher guest concentractions than those depicted in Figure 5, receptor curve and reference curve continue to diverge.
