A block copolymer containing P3HT and C(60) is synthesized and subjected to single-molecule spectroscopy (SMS) and AFM studies to investigate the impact of the C(60) on the P3HT chain conformation and the phase-separation behavior upon annealing, respectively. Both the SMS and the single-molecule polarization investigations indicate that the grafting of the C(60)-containing block to the P3HT moiety does not significantly change its conformational structure. AFM studies on thin films of the block copolymer indicate that they are stable with microphase separation, while blended films of the block-copolymer precursor (without C(60)) with PCBM undergo macroscale phase separation upon thermal annealing.
