Fig. 2: GIWAXS and simulated data.

a, d, g GIWAXS diffraction patterns of IDTT-CX-TIC neat films and (b, e, h) the corresponding in-plane and out-of-plane line-cut profiles. c, f, i The simulated results of IDTT-CX-TIC unit cells. The major molecular packing peaks with the detailed peak labeling was translated from single crystal to thin film. It can be seen that the major diffraction peaks of IDTT-CX-TIC films can be well traced from single-crystal unit cell.
