We present the pressure area isotherms for Langmuir films made of calix[8]arene, the calix[8]arene/C{sub 60} complex, and the calix[8]arene/C{sub 70} complex, all of them measured at 306.1 K. A Brewster angle microscope was used to observe the phases shown by {Pi}-A isotherms. In these three cases, we found a solid phase and its solid-gas coexistence but no expanded liquid phases. The Langmuir films of calix[8]arene and the calix[8]arene/C{sub 60} complex are very similar. The experimental information is consistent with the assumption that C{sub 60} is situated inside the cavity of calix[8]arene. The Langmuir films of calix[8]arene and the calix[8]arene/C{sub 70} complex are not very similar; we present a discussion to explain the origin of this difference. 23 refs., 5 figs.
