A new metallofullerene Lu@C 82 has been isolated with good purity using polar solvent extraction and HPLC techniques. XPS, EPR and UV-Vis-Nir spectroscopic techniques are employed to characterize the mono-metallofullerene Lu@C 82 . Our results suggest that the encaged Lu atom donates approximately t
La@C 82 is recognized by an isophthaloyl-bridged porphyrin dimer forming a stable 1:1 supramolecular complex with an association constant K assoc = (67.3 ยฑ 3.2) ร 10 3 M ร1 .
