Orientation of conducting oligomers from simple solution casting is an key factor to enhance the charge carrier mobility of organic thin fm transistors (OTFT). For this purpose, we prepared oligo(a-sexithiophene)-block-oligo(ethylene glycol) (OSBPEO) which shows self-orientation property depending on the surface energy of provided substrate. Using ink-jet printer, OTFTs were printed on a flexible plastic film using OSBPEO solution , and electrical characteristics of the printed OTFTs were investigated. Oriented molecular structure of OSBPEO was confirmed with STM and X-ray diffractomater after the deposition using simple ink-jet printing. |
