Tuning by Dip-Coating

Author: Kira Welter

Dip-coating could become an interesting route to generate unique microstructures of organic semiconductors on a large scale for applications in organic field-effect transistors (OFETs).

Scientists at the Max Planck Institute for Polymer Research, Mainz, Germany, have applied a simple dip-coating method to control the organization of small organic molecules with semiconducting properties on a surface. W. Pisula, K. Müllen and colleagues describe the fabrication of long-range well-aligned fibers from a soluble heterotriangulene derivative using this technique.

They explain that the introduction of such aligned fibrous microstructures into OFETs is currently under investigation.
