a–c Two-dimensional GIWAXS patterns and in-plane (solid lines) and out-of-plane (dashed lines) cuts of the neat films; d–f Two-dimensional GIWAXS patterns and in-plane (solid lines) and out-of-plane (dashed lines) cuts of blend films; g Time-resolution photoluminescence (TRPL) spectrum of donor and acceptors in neat films; h Transient kinetic traces of PM6 ground state bleaching (GSB) probing at around 630 nm for the blend films.
