利用核反应堆产生的中子照射富勒烯C70合成了新型碳纳米分子C141.高效液相色谱法分离纯化结果表明,这种奇数富勒烯二聚体分子可以在空气中稳定存在.基质辅助激光解析飞行时间质谱分析表明在激光作用下,C141解离生成的主要碎片为C71和C70·与C70比较,C141在可见光区的吸收明显减弱.实验结果表明这种新的核反应合成富勒烯二聚体的方法对生成C70-X-C70这一类型的碳纳米分子具有高度的选择性.
A new type of carbon nano-molecule C141 was synthesized by irradiation of fullerene C70 with neutron produced by a nuclear reactor.The separation and purification of high performance liquid chromatography showed that this kind of odd-numbered fullerene dimer molecules could stably exist in the air.Matrix- Time-of-flight mass spectrometry analysis showed that the major fragments generated by C141 dissociation under laser irradiation were C71 and C70 · Compared with C70, the absorption of C141 in the visible region was significantly reduced.The experimental results show that this new nuclear reaction synthesizes fullerene dimer Method is highly selective for the generation of C70-X-C70, a type of carbon nanomolecule.
