Multibranched C60 micro/nanocrystals fabricated by reprecipitation method

We found that monodispersed C-60 micro/nanocrystals (M/NCs) with unique multibranched structures can be fabricated by reprecipitation method, using m-xylene and 2-propanol as good and poor solvents, respectively. The resulting C60 M/NCs had a hexagonal crystal structure and was found to be a kind of crystal solvates in which the molar ratio Of C60 to in-xylene was 3 : 2. C-60 M/NCs seem to be important nanoparts in an integrated device.
