Transmission electron microscopy investigation of fullerene nanowhiskers and needle-like precipitates formed by using C60 and (η2-C60)Pt(PPh3)2

Nanowhiskers and needle-like precipitates obtained by the liquid-liquid interfacial precipitation method for the systems of isopropyl alcohol and toluene solutions of C-60 and (eta(2)-C-60)Pt(PPh3)(2) were examined by transmission electron microscopy. Morphology of the C-60 precipitates was remarkably changed by the addition of (eta(2)-C-60)Pt(PPh3)(2) in the C-60 toluene solution, and capsular needle-like crystals of C-60 were formed. C-60 cages were found to be directly contacted along the growth axis of (eta(2)-C-60)Pt(PPh3)(2) needle-like crystals.
