Transmission electron microscopy investigation of tubular and capsular needlelike crystals of C_(60) produced by the liquid-liquid interfacial precipitation method

摘要

Tubular and capsular needlelike crystals of C_(60) 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 (eta~2-C_(60))Pt(PPh_3)_2 to the toluene solution of C_(60) produced various morphologies of hollow C_(60) crystals. This paper gives the first report on the formation of structures we named "C_(60) nanotubes."
