摘要
C_(60) and C_(70) single crystals free from solvent contamination grew from their vapour. Large C_(60) crystals up to a size of about 5 mm × 3 mm × 3 mm and C_(70) crystals about 1 mm × 1 mm × 1 mm were obtained. C_(60) crystals with fee structure showed two types of morphological faces, namely {111} and {100 },frequently with twinning on {111} face. C_(70) crystals obtained have a hop structure with a = 10. 1 andc=16. 7 DSC and X-ray diffraction analysis indicated that C(70) crystal underwent phase transition below 100 ℃ Morphological observation suggests that the growth of C(60) and C(70) single crystals is based on layer spreading mechanism.
