Abstract

Abstract: A high temperature and high pressure method was used to efficiently and selectively extract metallofullerenes Ln_m@C_2n (Ln=Y, Gd, Tb) in a closed stainless steel autoclave under inert gas protection. 1,2,3-Trichlorobenzene was found to be more effective and selective for the extraction of Ln@C₈₂ (Ln=Y, Gd, Tb) from empty fullerenes and other metallofullerene species.

Key words: Metallofullerene, Empty fullerenes, High-temperature and high pressure extraction, Soot
