| Abstract
| - The particular behavior of a p-tert-butyl calix[8]arene derivative (C8A) has been studied at the air−waterinterface using surface pressure−area isotherms, surface potential−area isotherms, film relaxation measurements, Brewster angle microscopy (BAM), and infrared spectroscopy for Langmuir−Blodgett films. Thus, itis observed that the properties of the film, for example, isotherms, domain formation, and FTIR spectra,recorded during the first compression cycle differ appreciably from those during the second compression andfollowing cycles. The results obtained are interpreted on the basis of the conformational changes of the C8Amolecules by surface pressure, allowing us to inquire into the inter- and intramolecular interactions (hydrogenbonds) of those molecules. Thus, the compression induces changes in the kind of hydrogen bonds from intra-and intermolecular with other C8A molecules to hydrogen bonds with water molecules.
