| 中文摘要 | in view of the growing interest in endohedral lanthanide fullerenes, ce, as a typical +4 oxidation state lanthanide element, has been systematically studied. the synthesis, extraction and electronic structure of ce@c-2n are investigated. soot containing ce@c-2n was synthesized in high yield by carbonizing ceo2-containing graphite rods and are back-burning the cec2-enriched cathode deposit in a dc are plasma apparatus. ce@c-2n, dominated by ce@c-82, can be efficiently extracted from the insoluble part of the soot after toluene soxhlet extraction by pyridine at high temperature and high pressure in a closed vessel. about 60% ce@c-2n (2n = 82,80,78,76) and 35% ce@c-82 can be enriched in the pyridine extract. this fact is identified by desorption electron impact mass spectrometry (dei ms). the electronic structure of ce@c-2n is analyzed by using x-ray photoemission spectroscopy (xps) of pyridine-free film. it is suggested that the encapsulated ce atom is in a charge state close to +3 and was effectively protected from reaction with water and oxygen by the enclosing fullerene cage. unlike theoretical expectation, the electronic state of ce@c-82 is formally described as ce+3@c-82(3-).
