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 combina-tion 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 syn-thesized 9, 9-bianthracene are fabricated for the first time. Its field-effect mobility is as large as 0.067 cm2 /(V.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.
