“…The results showed that, in all cases, the saturated fullerene solutions had a higher evaporation rate than pure solvents. These results are in excellent agreement with what Ginsburg et al have reported [37][38][39][40][41]. The unique finding of our current results is the very clear maxima and minima behavior measured.…”

We investigate the effect of C60 fullerene nanospheres on the evaporation kinetics of a number of aromatic solvents with different levels of molecular association, namely, benzene, toluene, and chlorobenzene. The dependence of the evaporation rate on the fullerene concentration is not monotonic but rather exhibits maxima and minima. The results strongly support the notion of molecular structuring within the liquid solvent controlled by the nature of the fullerene/solvent interaction and the level of molecular association within the solvent itself.

“…Interestingly, in the blended films, the characteristic diffraction peaks found in [C60]PCBM films (Fig. 3) www.MaterialsViews.com www.afm-journal.de and powders, [13] at around 2u ¼ 128 and 2u ¼ 208 are clearly visible, as they are very intense and do not overlap with those attributed to the polymer. Both phases are therefore partially ordered even in the as-cast film.…”

Carbon bridged (C‐PCPDTBT) and silicon‐bridged (Si‐PCPDTBT) dithiophene donor–acceptor copolymers belong to a promising class of low bandgap materials. Their higher field‐effect mobility, as high as 10−2 cm2 V−1 s−1 in pristine films, and their more balanced charge transport in blends with fullerenes make silicon‐bridged materials better candidates for use in photovoltaic devices. Striking morphological changes are observed in polymer:fullerene bulk heterojunctions upon the substitution of the bridging atom. XRD investigation indicates increased π–π stacking in Si‐PCPDTBT compared to the carbon‐bridged analogue. The fluorescence of this polymer and that of its counterpart C‐PCPDTBT indicates that the higher photogeneration achieved in Si‐PCPDTBT:fullerene films (with either [C60]PCBM or [C70]PCBM) can be correlated to the inactivation of a charge‐transfer complex and to a favorable length of the donor–acceptor phase separation. TEM studies of Si‐PCPDTBT:fullerene blended films suggest the formation of an interpenetrating network whose phase distribution is comparable to the one achieved in C‐PCPDTBT:fullerene using 1,8‐octanedithiol as an additive. In order to achieve a balanced hole and electron transport, Si‐PCPDTBT requires a lower fullerene content (between 50 to 60 wt%) than C‐PCPDTBT (more than 70 wt%). The Si‐PCPDTBT:[C70]PCBM OBHJ solar cells deliver power conversion efficiencies of over 5%.

“…The choice of PMMA as the basic material for the matrix of composite films is related to the fact that PMMA samples are practically structureless up to the nanoscale level: Scattering intensities remain constant throughout the assessable range of scattering angles in their small angle X ray patterns [4].…”

The effect of fullerene C 60 on the structure and mechanical properties of poly(methyl methacry late) films are studied via the methods of X ray diffraction, mechanics, and optical and atomic force micros copy. The findings of this study are verified with the use of the data obtained for amorphous and semicrystal line samples of other polymers, primarily carbochain polymers of the vinyl series, such as polyethylene, polypropylene, and polystyrene.
