%X We synthesize and purify 9,9'-bianthracene with the purity up to 96.4 %. The electronic and crystallographic structures of 9,9'-bianthracene are studied. The results of a joint experimental investigation based on a combination of x-ray diffraction (XRD) spectra, hydrogen nuclear magnetic (HNMR) spectra, infrared absorption (FT-IR) spectra, and mass spectra (MS) of 9,9'-bianthracene are obtained. The uniform compact film is observed by an atomic-force microscope (AFM). Organic field effect transistors (OFETs) with an active layer based on the synthesized 9,9'-bianthracene are fabricated for the first time. Its field-effect mobility is as large as 0.067cm2/(V&#12539;s) and the on/off ratio is above 5×104. The result demonstrates that the oligomerization of a small semiconductor molecule is an effective method to develop high-mobility organic semiconductors.
