“…Overall, according to the above DSC data, the attachment of the bulky C 60 either as the end group in the case of dyads, or linked to the main chain/side chain junction point in the case of brush polymer, appeared to have some minor impact on the crystallization behavior of the P3HT units. Moreover, all XRD profiles ( Figure 17 ) of P3HT-(CH 2 ) 3 -VIM-C 60 and brush polymer adduct P[P3HT-(CH 2 ) 3 -VIM-C 60 ] showed a sharp peak at 5.30° to 5.53°, which is associated with the (100) reflection of P3HT [ 48 , 49 , 50 , 51 ]. In addition, intense peaks at 10.7° to 10.9°, as well as those appeared at 20.66° and 23.1°, associated with the adduct formation, were also observed.…”
