Preparation and deposition of stable monolayers of fullerene derivatives

Abstract

Two new fullerene derivatives have been synthesized, which tend to form Langmuir monolayers. Robust monomolecular layers are formed at the air/water interface, that can be transferred onto hydrophilic substrates by Langmuir–Blodgett or Langmuir–Schaefer techniques. The measured areas per molecule (105 Ų for 1a dropped from a deuteriochloroform solution at 20 °C) reach those expected for a true monolayer of C₆₀ at the air/water interface.
