Chromatographic retention relationships between Ce-, Gd-, La-, and Y- containing endohedral metallofullerenes and a [2-(1-pyrenyl)ethyl]silyl-silica stationary phase were studied using toluene as eluent. Measurements are discussed in comparison to those of empty fullerenes. Both the extraction and chromatographic elution behaviour of the metallofullerenes reflect their polar nature and allow inferences regarding the presence of a dipole moment in M@C{sub 82}. 55 refs., 4 figs.
