FORMATION AND SPECIAL SOLUBILITY OF ENDOH EDRAL THULIUM METALLOFULLERENES

Endohedral metallofullerenes Tm@C-2n were synthesized with the carbon- arc discharge method of activating the Tm2O3-containing graphite anode in situ and back-burning technique, Toluene soxhlet extraction, tolue ne and pyridine high-temperature and high-pressure extraction techniqu e were employed for the effective extraction of Tm@C-2n. The formation of Tm@C-2n was confirmed by LD-TOF and DEIMS characterization. The ma ss spectrometric results indicate that Tm@C-2n have a better solubilit y in toluene and worse solubility in pyridine than other metallofuller enes.
