Abstract

Tubular and capsular needlelike crystals of C60 with a few hundreds nanometers to about one micrometer in diameter were discovered among the precipitates prepared by the liquid–liquid interfacial precipitation method. Addition of a small amount of (η2–C60)Pt(PPh3)2 to the toluene solution of C60 produced various morphologies of hollow C60 crystals. This paper gives the first report on the formation of structures we named “C60 nanotubes.”
