含铥金属富勒烯的生成及其特殊的溶解行为

金属富勒烯的合成及结构研究是当前富勒烯化学研究的重要内容1]．一些稀土金属元素，如Sc2]、Y3]及大部分斓系元素（La、Ce、Nd、Sin、Eu、Gd、Tb、Ho）4]形成的金属富勒烯已被合成出来．但仍有一些稀土富勒烯的合成尚未见报道，使人们难以对金属富勒烯的形成机制及物化性能作出全面的判断．本文采用原位活化、交换电极回放电弧放电及两步提取法首次得到含锡金属富勒烯．通过空白对比实验确定了Tin＠C。怕9生成．对甲苯及毗院提取液的质谱研究表明含镀金属富勒烯具有区别于其它金属富勒烯的特殊的溶解性能，显示出其可能具有独特的…

Formation and Special Solubility of Endohedral Thulium Metallofullerenes

Endohedral metallofullerenes Tm@C2n were synthesized with the carbon-arc dis-charge method of activating the Tm2O3-containing graphite anode in situ and back-burning technique. ToIuene soxhlet extraction, toluene and pyridine high-temperature and high-pres-sure extraction technique were employed for the effective extraction of Tm@C2n. The forma-tion of Tm@C2n was confirmed by LD-TOF and DEIMS characterization. The mass spectro-metric results indicate that Tm@C2n. have a better solubility in toluene and worse solubility in pyridine than other metallofullerenes.
