Brewster angle microscopy of fullerene monolayers

The aim of this paper is to present a direct observation by means of Brewster angle microscopy of Langmuir films made of C60 along the process of their compression. We found coexistence of a gas and a condensed phase at low area densities. Our results agree with the formation of multilayers even at low area densities. We made compressions of the films at several speeds, with rapid compressions we found that the condensed phase formed foam-like structures and circular domains of different sizes at very small area densities
