Figure 4. XRD and UV−vis absorption of the modification layers.

Figure 4

(a) XRD patterns of the M-C10 thin film before and after annealing, together with that of M-C0 film obtained by vacuum-deposition. The M-C10 molecules adopt a layer-by-layer packing motif in annealed thin film as evidenced by the diffraction peak appears after thermal treatment. Inset: schematic diagram of molecular packing styles of amorphous and thin film phase. (b) XRD characterization of pentacene grown on M-C0, non-annealed M-C10, and annealed M-C10 modification layers. UV−vis absorption spectra of (c) M-C0 and (d) M-C10 in solution and thin film states (before and after annealing). Inset: molecular structures of M-C10 and M-C0.
