Patterning functional organic molecules based on the liquid behavior — •Hong Wang, Wenchong Wang, and Lifeng Chi — Physikalisches Institut and Center for Nanotechnology (CeNTech), Universität Münster, 48149 Münster, Germany

Small organic molecules were reported to have the probability to perform like liquid on a surface under vacuum condition, which enable us to fabricate functional organic patterns through focusing on the liquid behavior of it. Here we demonstrate the versatility of the technique in vacuum chamber to create organic hetero-patterns on hierarchically pre-pattern surface through temple-directed growth to locate N,N'-Di[(N-(3, 6-di-tbutyl-carbazyl)ndecyl] quinacridone (DtCDQA) at pre-defined area firstly, and then anneal at optimized temperature to tune the pattern in situ. Meanwhile, the controlling of organic liquid can also be taken in ambient condition. By using N -ethyl- d -glucamine (NEDG) as the liquid source, we succeeded to pattern organic films on Au stripes directly through self-driven microfluidics. Furthermore, the fluid can be used to transport other functional molecules, e.g., dye molecules, creating multicolored patterns in one step.
