摘要： 将采用液液界面析出法在甲苯/叔丁醇体系中培养的二维（2D）富勒烯C60片状晶体置于含2%(体积分数)间二甲苯的异丙醇中24 h，则该2D片状晶体转变成一维（1D）晶须。通过光学显微镜，扫描电子显微镜，红外光谱，拉曼光谱，X射线衍射法对其形貌及组成、晶型进行了表征。结果表明：1D富勒烯C60晶须与2D C60片状晶体具有相同的分子组成和晶型。

Abstract: The twodimensional (2D) C60 flake crystals were synthesized by liquidliquid interfacial precipitation (LLIP). The C60 crystal was placed in isopropanol containing 2% （volume fraction） mxylene for 24 h, and then the 2D crystal was transformed into onedimensional (1D) whiskers. The morphology, component and structure were characterized by optical microscopy (OM), scanning electron microscopy (SEM), infrared spectrometry (IR), Raman spectroscopy and Xray diffraction (XRD), respectively. The results showed that the 1D C60 whiskers have the same component and crystal structure with 2D C60 crystals.

Key words: liquidliquid interfacial precipitation; fullerene C60; morphology transformation; crystallization
