Zusammenfassung

A method concerning step-edge-induced area-selective growth for the patterning of aromatic organic molecules is proposed. Based on such a growth mechanism, crack-free, organic crystalline films and the growth of different molecules at defined locations can be achieved. The figure shows a schematic representation of the separation of molecules by nucleation-sites recognition.
