Abstract
Chromatographic retention relationships between Ce-, Gd-, La-, and Y-c ontaining endohedral metallofullerenes and a [2-(1-pyrenyl)ethyl]silyl -silica stationary phase were studied using toluene as eluent. Measure ments are discussed in comparison to those of empty fullerenes. Both t he extraction and chromatographic elution behavior of the metallofulle renes reflect their polar nature and allow inferences regarding the pr esence of a dipole moment in M@C-82.
