ABSTRACT

Fullerene nanowhiskers (FNWs) are thin crystalline fibers composed of fullerene molecules, including C60, C70, endohedral, or functionalized fullerenes. FNWs display n-type semiconducting behavior and are used in a diverse range of applications, including field-effect transistors, solar cells, chemical sensors, and photocatalysts. Alkali metal-doped C60 (fullerene) nanowhiskers (C60NWs) exhibit superconducting behavior. Potassium-doped C60NWs have realized the highest superconducting volume fraction of the alkali metal-doped C60 crystals and display a high critical current density (Jc) under a high magnetic field of 50 kOe. The growth control of FNWs is important for their success in practical applications. This paper reviews recent FNWs research focusing on their mechanical, electrical and superconducting properties and growth mechanisms in the liquid–liquid interfacial precipitation method.

Mentions: Fullerene nanofibers can incorporate either one or multiple types of fullerenes. This enables formation of both monocomponent and multicomponent structures. Examples of monocomponent structures include C60NWs, C70 (fullerene) nanowhiskers (C70NWs), C60 or C70 (fullerene) nanotubes (C60NTs or C70NTs), [23, 25, 28], and FNWs composed of C60[C(COOC2H5)2] molecules (C60[C(COOC2H5)2]NWs). Examples of multicomponent fullerene nanofibers include two-component C60–C70 NWs [29], two-component C60–C70 NTs [23], two-component C60–C60[C(COOC2H5)2] NWs [19], and two-component C60–(η2-C60)Pt(PPh3)2 NWs [22]. Figure 1 shows the classification of fullerene nanofibers.
