Fig. 3: Molecular dynamic simulations of the pristine and annealed (R)-P(NDI2MH-T2).

a Snapshot of the pristine film structure. b Snapshot of the annealed film structure. c Radial distribution functions of the two systems. d Probability distribution of the mean square radius of gyration for the two systems. e Typical structure of the pristine film, with pink spheres representing spheres drawn with the mean square radius of gyration as the radius. f Typical structure of the annealed film, with pink spheres representing spheres drawn with the mean square radius of gyration as the radius.
