自Kratschmer等人,发现有效的制备富勒烯的方法之后,富勒烯的研究已成为科学研究的热点之一.为了这种材料的深入研究与开拓潜在的应用领域,制备C_(60)晶体是非常有意义的,尽管这方面已有不少报道,但要制备出大体积无缺陷的单晶,还有很多工作要做.我们在用甲苯溶液逐次生长法生长C_(60)晶体的过程中,发现C_(60)甲苯溶深的结晶形貌与C_(60)和C_(70)的相面比例有较大关系,并首次观察到富勒烯甲苯溶液结晶的分形现象,为晶体生长动力学的研究提供了一些有意义的结果.
Since Kratschmer et al. Found an effective method for preparing fullerenes, the study of fullerenes has become one of the hot topics in scientific research.In order to further study and exploit potential applications of this material, the preparation of C 60 crystals It is very significant that although many reports have been made in this respect, there is still a lot of work to be done to prepare a large volume of defect-free single crystals.We are in the process of growing C 60 crystals by successive growth of toluene solution It was found that the crystal morphology of toluene solution of C 60 has a great relationship with the phase ratio of C 60 and C 70 and the fractal phenomenon of the crystallization of fullerene toluene solution was observed for the first time. Kinetic studies provide some meaningful results.
