“…The tubular structure of the PAni-EB-doped FW is due to the formation of C 60 -NMP charge transfer (CT) complexes (21,22). The C 60 fullerene acts as the electron acceptor and Pleated Surface Morphology of C 60 Fullerene Nanowhiskers 711 the NMP serves as donor since it has a nitrogen atom with lone pair electrons.…”

“…Figure 7 shows the possible mechanism for the intermolecular interaction between FW and imine group of PAni. The CT causes the interaction between the polymer and the C 60 from electron-rich PAni to electron-deficient FW (21,22). This interaction then resulted to the physical chain entanglement of PAni to the fullerene fiber.…”

“…The conjugated polymer adhered along the corners of the hexagonal cross section due to the relatively higher free energy in the corner sites of the FW in addition to the ionic bonding between the two constituents. The hybrid has a tubular structure because of the lone pair electrons present in both NMP and PAni causing dissolution inside the whisker (22). This hybrid with tubular structure and high surface area could serve as host or capsules for different chemical reactants that may lead to the creation of a material that has unique chromatic changes in response to thermal, mechanical and chemical stimuli.…”

The addition of polyaniline emeraldine base dissolved in N-methyl-2-pyrrolidone (PAni/NMP) on fullerene C 60 whiskers (FW) by direct-mixing technique resulted to the formation of a hybrid material herein called FW/PAni hybrid. The FW/PAni hybrid has a tubular structure with pleated surface texture. It is thinly coated with PAni and has a higher surface area relative to pristine FW and PAni. Beneath the amorphous outer covering, the hybrid shows a crystalline structure as shown by high resolution TEM and selected area electron diffraction. Charge transfer (CT) interaction from electron-rich PAni to electron deficient FW may have resulted to the physical chain entanglement of PAni to FW. The tubular structure of the hybrid is likely caused by the lone pair electrons present in both NMP and PAni causing dissolution inside the whisker. The FW/PAni hybrid having a large surface area and narrow pore size distribution has potential use as hydrogen adsorbent for fuel cell applications, catalysts, and templates for nanofabrication.

C 60 nanotubes with diameters of smaller than 500 nm are fabricated by a modified liquid-liquid interfacial precipitation method. In situ angle dispersive synchrotron x ray diffraction and Raman scattering under pressures have been employed to study the structure evolution of the C 60 nanotubes. The experimental results indicate that there is a pressure induced irreversible amorphization at 40.1 GPa. An isostructural phase transition occurs in the pressure range of 9.29-12.2 GPa, which is probably relative to the changes in the bonding type of C 60 nanotubes.

The single-crystalm icro/nanostructures of fullerene species, namely C 60 and C 70 ,h ave been previously studied, but studies on the morphology and properties of higher fullerenes have rarely been reported due to the limited amount of samples andt heir ellipsoidal isomeric structures. Herein, we report the formation of three-dimensional (3D) micro-cubes and micro-diceo fahigherf ullerene (C 78)v ia a facile liquid-liquidi nterfacial precipitation (LLIP) method. The micro-cubeswereprepared by regulating the concentration of C 78 in trimethylbenzene(TMB) and the volume ratio of TMB and isopropanol. Interestingly,t he micro-cubesa re transformed into micro-dice with an open-hole on each crystal face by simply shaking the solution. X-ray diffraction and Fourier-transform infrareds pectroscopic studies revealed a simple cubic unit cell with al attice constant of 10.6 and intercalated TMB molecules in both crystals.T he C 78 cubic and dice-like microstructures exhibited enhanced photoelectrochemical and photoluminescence properties compared with pristine C 78 powder,i ndicating their potential applications as photodetectors and photoelectric devices.
