p-Channel organic semiconductor based on hybrid acene-thiophene molecules for thin-film transistor applications

The structural and electrical characterization of two new p-channel organic semiconductors from the class of hybrid acene-thiophene materials, 5,5'-bis(2-tetracenyl)-2,2'-bithiophene (1) and 5,5'-bis(2-anthracenyl)-2,2'-bithiophene (2) is reported. The thin-film structures are examined using wide-angle X-ray diffraction (XRD), grazing incidence X-ray diffraction (GIXD), and atomic force microscopy (AFM).
