Figure 1. Topography of P(NDI2OD-T2) submonolayer and films deposited on glass substrates.

Figure 1

AFM images of P(NDI2OD-T2) films spin-coated from solutions with concentration of a) 0.1 gl−1, b) 0.5 g l−1, c) 0.8 g l−1, d) 0.9 g l−1, e) 1 g l−1 and f) 5 g l−1. In g) the profile analysis of a), b), c) and f) is reported. h) Sketch of the bar-coating process. i) AFM picture of a submonolayer deposited by bar-coating a 0.5 g l−1 solution in mesitylene. j) AFM picture of a highly oriented film realized by bar-coating of a 5 g l−1 solution in mesitylene. Scale bars are 1 μm.
