ABSTRACT:
A star-shaped oligothiophene-arylene derivative in which an oligothiophene having p-type semiconductor characteristics is bonded to an arylene having n-type semiconductor characteristics positioned in the central moiety of the molecule and forms a star shape with the arylene, thereby simultaneously exhibiting both p-type and n-type semiconductor characteristics. Further, an organic thin film transistor using the oligothiophene-arylene derivative. The star-shaped oligothiophene-arylene derivative can be spin-coated at room temperature, leading to the fabrication of organic thin film transistors simultaneously satisfying the requirements of high charge carrier mobility and low off-state leakage current.
