Abstract
Endohedral metallofullerenes Tb@C2n were synthesized and extracted with high-yield by K-H carbon-are evaporation and an effective pyridine extraction technique at high-temperature high-pressure. Laser-desorption-ionization time-of-flight (LD-TOF) mass spectrometry, X-ray photoelectron spectroscopy (XPS), solid-state fluorescent emission spectroscopy and gas phase derivation reaction with the self-chemical ionization mass spectrometric ion system of vinyl acetate were employed for studying the electronic structures, fluorescent properties and gas phase reactivities of metallofullerenes Tb@C2n. The experimental results suggest that endohedral metallofullerenes Tb@C2n would have the approximate structures of Tb3+@C2n 3+ similar to other metallofullerenes, good fluorescent emission properties and active reactivities in gas phase ion-molecular reactions.
