This paper describes details of a reorganization and collapse taking place when a C18-ferrocene-carboxamide Langmuir monolayer is compressed in a Langmuir trough at the surface of a 1 M HClO4 solution. Surface pressure/area isotherms were recorded and analyzed regarding hysteresis effects and compressibility. Other techniques employed include Delta V measurements, cyclic voltammetry, ellipsometry, and atomic force microscopy(AFM). A dynamic transformation is initiated at the moment the surface pressure starts to rise. This comprises the simultaneous formation of two new phases from the liquid expanded phase that is initially present. One of the phases consists of nuclei of the three-dimensional phase that is formed at collapse and we propose that the other is a liquid condensed phase.
