Figure 1

Molecular structure of PDIF-CN2 (a). The morphology of a film deposited at rate R = 0.07 nm/min acquired on a scan window of 2 × 1 μm2 with the line profile acquired along the red line are shown (b). The characteristic length w, ξ and λ are depicted as illustration. In the bottom part of the image three 10 × 10 μm2 AFM topographies are presented: the as-grown surface after few hours from the molecular beam switch off (c), a mixed surface (d) and a completely ripened surface after 1 year (e). The white markers are of size 1 μm. In the insets, images of 2 × 2 μm2 zoom of the images (c–e) are presented. The red markers are of size 0.5 μm.
