Orientation of conducting oligomers from simple solution casting is an key factor for the practical use of organic thin film transistors (OTFT). In this presentation, we would like to show the possibility of control the orientation of conducting oligomers through intra crystallization forces generated between a surface and a highly crystalline oligomer. For this purpose, we prepared oligo(3,4-ethylenedioxythiophene)-block-oligo(ethylene glycol) which shows self-orientation property depending on the surface energy of provided substrate. Its structure was confirmed with Nuclear Magnetic Resonance (NMR) and Fourier Infrared(FT-IR). X-ray diffractomater examined the crystalline structure of the conducting block oligomer. The electrochemical and physical proprieties were characterized through Atomic Force Microscope (AFM) and Scanning tunneling microscope (STM). |
