Biomineralization is a typical methodology developed by nature to produce calcium-based materials. A method mimicking this process has nowadays become popular for the preparation of artificial organic-inorganic hybrids. Here, Cu-3(PO4)(2) crystals with a flowerlike morphology have been prepared using water-soluble derivatives of fullerene C-60 as templates. In a typical system, flowerlike crystals of Cu-3(PO4)(2) (denoted FLCs-Cu) were obtained by simply dropping an aqueous solution of CuSO4 into phosphate buffered saline (PBS) containing a highly water-soluble multiadduct of C-60 (fullerenol). The best condition for the preparation of FLCs-Cu appeared at 0.20 mg.mL(-1) fullerenol and 0.10 mol.L-1 PBS. During the formation of FLCs-Cu, fullerenol acts as a template and its content in FLCs-Cu is trace (less than 5% by atom) as confirmed by scanning electron microscopy mapping and thermogravimetric analysis. This feature makes fullerenol reusable, and the FLCs-Cu can be prepared repeatedly using the same fullerenol aqueous solution at least 10 times without a noticeable change in the morphology. The N-2 adsorption/desorption isotherm showed that the doping of fullerenol increased the specific surface area of the Cu-3(PO4)(2) crystal. When fullerenol was replaced by C-60 monoadducts that are cofunctionalized with a pyrrolidine cation and oligo(poly(ethylene oxide)) chains, FLCs-Cu can form as well, indicating that the strategy of using water-soluble C-60 derivative as a template to get FLCs-Cu is universal. As a typical example of practical applications, the photocatalytic activity of the FLCs-Cu was investigated toward the degradation of dyes including rhodamine B and rhodamine 6G. In both cases, efficient photodegradation has been confirmed.
