Figure S1 Photoluminescence quenching experiments. Left: P3HT (black) and P3HT/1 4:1 (blue). Right: P3HT (black), P3HT/2 9:1 (red) and P3HT/2 1:1 (blue).

Figure S2 Specular X-ray diffractograms for blends of P3HT with the monomeric acceptor 1, traces are in order of increasing acceptor loading and in each case annealing was performed for 3 minutes at each temperature.
