Optical and structural studies of DPP2T and DPP2T/PS films. (A) Chemical structures of DPP2T and PS. (B) Optical absorption spectra of DPP2T and DPP2T/PS (15/85 wt % ratio) in solution and as solid-state films. (C) Optical transmittance (Tr) spectra of DPP2T and DPP2T/PS films. (Inset) Optical image of a pure DPP2T film and a DPP2T/PS film on glass substrates. The t of both films is ∼10 nm. (D) TEM images of DPP2T and DPP2T/PS films. (Scale bar, 200 nm.) (E) Normalized 2D GIWAXS patterns of DPP2T and DPP2T/PS films. (F and G) Schematic illustrations of the structural morphologies of (F) DPP2T and (G) DPP2T/PS films.
