One-step synthesis of C60 nano-assemblies at different temperatures

• Nanoassemblies of C60 nanorods were fabricated with solution evaporation method.
• The assembling form of C60 nano-assemblies depended on growth temperature.
• The shapes of C60 nano-assemblies were related to the size of seed crystals.

Nanoassemblies (microtubes, microrods, nanoflowers and nanorod arrays) composed of C60 nanorods, were fabricated with a solution evaporation method. The structures and the growth mechanism of C60 nano-assemblies were investigated. The C60 microtubes obtained at room temperature had a hexagonal structure, C60 microrods and nanoflowers synthesized at 0 °C and − 15 °C had a similar mixed hexagonal structure, and the C60 nanorod arrays had a structure indexed as an orthorhombic structure. The morphology of the C60 nano-assemblies depended on the shape and size of the seed crystals, which were closely related to the precipitation process from the saturated solution at different temperatures.

We have synthesized various C60 nano-assemblies composed of C60 nanorods with a one-step solution evaporation method at different temperatures.Figure optionsDownload as PowerPoint slide
