摘要

A new [70]fullerene dimer consisting of 141 carbon atoms was first synthesized by a new method with neutron irradiation of [70]fullerene. The results of separation and isolation with two-step HPLC(high performance liquid chromatography) show that this odd-numbered fullerene dimer is stable in air. Laser induced dissociation of C_(141) mainly yields fragmental species C_(70) and C_(71). The UV-vis spectrum of C_(141) shows that its vis feature is diminished as compared to that of C_(70). Experiments indicate that this new method for synthesis of fullerene dimers with neutron irradiation has a high selectivity for formation of C_(2n)-X-C_(2n) type carbon nanomolecules.
