    • The solution studies offer the advantage of a precise determination of association constants, stoichiometries, and complex geometries. This characterization becomes much more difficult in a lipid monolayer.

    • Quite recently, calixarene 1,3-bisphosphonates with alternating hydrophilic and Hydrophobie groups have been prepared and integrated into monolayers entirely consisting of two-dimensional condensed-phase domains: Vollhardt, D.; Gloede, J.; Weidemann, G.; Rudert, R.

    • -8 M equimolar aqueous solution of the histone protein with the calixarene host, we obtained a clean ESI-MS spectrum. It featured prominent molecular ion peaks for the 1:1, 1:2, and 1:3 complex, with the highest intensity residing in the 1:2 peaks.

    • In high excess, NaCl and HEPES themselves interact with the receptor molecule and are less pronounced with the stearic acid monolayer; however, the large additional increase with NaCl, due to the specific calixarene protein interaction, remains constant throughout the entire concentration range: (a) Shahgaldian, P.; Coleman, A. W. Langmuir 2001, 17, 6851-6854.

    • -8 M. This is clearly related to what BSA does in nature: it binds to fatty acids which have been released to the blood stream and leads to a 1000-fold increase in their solubility. Apart from BSA, thrombin, and to a small extent ferritine, the dodecamer and chymotrypsin also interact with the stearic acid monolayer.
