Fig. 2. Plot of the fraction of aggregates (αagg) against temperature for (a) C3OPV and (b) C3PBI individual assemblies, and (c) for C3OPV and C3PBI as a 1 : 1 mixture in toluene (1 × 10–4 M). C3OPV (
), C3PBI (
) and curve fitting (
). Absorbance was monitored at 425 and 527 nm for C3OPV and C3PBI, respectively, with a rate of cooling of 1 K min–1. Schematic illustration of the self-assembly pathway of (d) C3OPV and (e) C3PBI. Ke is the association constant and Ka is the activation constant expressing the degree of cooperativity.
