Ordered triple color patterns based on two dye molecules — •Wang Wenchong, Fuchs Harald, and Chi Lifeng — Physikalisches Institut and Center for Nanotechnology (CeNTech), Universität Münster, 48149 Münster, Germany

Functional, small molecular weight organic molecules have received great scientific and technological interest due to their promising potential applications in molecular electronics and optoelectronics. Since last two decades, exciting progress has been witnessed in both materials and film preparation that applied for organic field effect transistors (OFETs),light emission diodes (OLEDs), solar cells,Memories, Sensors, and so on. However, device processing techniques yielding high performances, high levels of integration and uniformity over large area are still underdevelopment. Template directed growth of molecules has been demonstrated as a promising technique for patterning,functionalizing materials at predefined areas and improving device performance.[1-3] Here, based on liquid behavior and solid solvation of molecuoes on patterned surface, the technique can further be applied to fabricate high resolution, ordered triple color patterns with only two molecules.
