On the preparation of Langmuir-Blodgett films of pyrrole derivatives

Abstract In this paper, we present a study of the preparation of Langmuir-Blodgett films of polymers obtained on a trough from mixtures made by pyrrole derivatives. In particular, the comparison between films obtained by different molar ratios of 3-hexadecyl-pyrrole to pure pyrrole is shown, in terms of the kinetics of the process and of the compressibility of the products obtained. Depending on the molar ratio in the composition of the mixtures, differences have been found in the structure of the co-polymer obtained and in the behaviour of the resulting film.
