C₆₀ crystals have potential applications in the optoelectronics, photoconducting devices and templated synthesis fields. However, their preparation is complex. A simple liquid-liquid interfacial precipitation method was used to fabricate hierarchically-organized C₆₀ crystals with various topographic characteristics, using 1,2,3,4-tetrahydronaphthalene as a good solvent, and isopropanol, ethanol or methanol as a poor solvent. Results indicate that the morphology and shape of the as-prepared C₆₀ crystals vary according to the solvent combination and the ratio of good to poor solvents. The SEM images of fractured surfaces and XRD patterns of the crystals reveal that the crystals are formed by the hierarchical organization of C₆₀ molecules at the molecular level to nanocrystals that are assembled into micrometer crystals. The crystals are composed solely of C₆₀ molecules, without polymerization and solvents, which are arranged in a face-centered cubic lattice. The surface roughness is increased by post washing with ethanol. The methodology described here is advantageous over the high-temperature conversion and solvent annealing methods reported previously.

C ₆₀晶体在光电，光电导器件和模板合成领域具有潜在的应用。但是，它们的准备很复杂。以1,2,3,4-四氢萘为良溶剂，以异丙醇，乙醇或甲醇为不良溶剂，采用简单的液-液界面沉淀法制备具有各种形貌特征的分层C ₆₀晶体。结果表明，所制备的C ₆₀晶体的形态和形状根据溶剂组合和良劣溶剂的比例而变化。断裂表面的SEM图像和晶体的XRD图谱表明，晶体是由C ₆₀的层级组织形成的分子在分子水平上被组装成微米级晶体的纳米晶体。晶体仅由C ₆₀分子组成，没有聚合和溶剂，它们以面心立方晶格排列。通过用乙醇进行后洗涤增加了表面粗糙度。本文所述的方法优于先前报道的高温转化和溶剂退火方法。
