We have synthesized C_<60> crystals using a simple liquid/liquid interfacial precipitation method in a mcrofluidic device. By controlling space, time, temperature, concentration, various C_<60> crystal morphologies were obtained including multiwalled tubes, open-ended hollow columns, dendrites, prisms, and needles. The C_<60> crystal morphologies were categorized mainly by temperature, and similar to the morphologies of snow crystals. This simple method yields complex geometries of C_<60> crystals quickly, and could be applied to all materials synthesis techniques that use liquid/liquid interfacial precipitation such as carbon crystals, protein crystals, clathrate hydrate crystals, and minerals.
