The structure of fullerene films and their metallocene doping
- Institute of Organometallic Chemistry, Nizhnii Novgorod (Russian Federation); and others
Hexagonal close-packed (HCP) C{sub 60} and C{sub 70} films have been prepared by the Langmuir method and examined by electron microscopy and electron-diffraction analysis. It has been shown that the vacuum deposition of a C{sub 60} + C{sub 70} mixture results in the formation of a film with small sized grains and a distorted C{sub 60}-HCP structure. The simultaneous deposition of C{sub 60} and ferrocene results in the formation of a film with a changed morphology and an electron-diffraction pattern that contains a variable amount of ferrocene depending on the experimental conditions. The electron-diffraction pattern corresponds to the presence of the known molecular complex C{sub 60}[(C{sub 5}H{sub 5}){sub 2}Fe]{sub 2}. The analogous simultaneous deposition of fullerene C{sub 60} and cobaltocene results in the formation of a C{sub 60} film stable in air and water, which contains carbon and cobalt (from the data of X-ray fluorescence, electron microscopy and microdiffraction). It has a different morphology and different diffraction patterns than pure C{sub 60} films and, depending on the cobaltocene content (relative to that of fullerene), appears to be a fullerite film doped with various amounts of cobaltocenium fulleride, which is an ionic compound.
