Dimensionally-integrated self-assembled fullerene crystals have received considerable interest for the possible applications in diverse fields including flexible optoelectronics device, field effect transistors, light emitting diodes, photovoltaic cells, sensors and photodetectors. Fullerenes in its self-assembled 1D or 2D forms display excellent physicochemical and optoelectronic properties including high electron mobility, high photosensitivity. Here, we present self-assembled fullerene crystals from zero to higher dimensions at liquid-liquid interface under the mild conditions of temperature and pressure (Fig. 1). We also discuss the recently developed novel technique for the expansion of fullerene nanomaterials into hierarchic macro- and mesopores architectures with crystallized
