摘要：
Star-shaped molecules with pyrene-containing pi-conjugated units linked by an organosilicon core (Py3Si and Py3C) were prepared and their applications to thin-film transistors (TFTs) and photovoltaic cells were studied. Bottom-contact type TFTs with spin-coated films of the star-shaped compounds as the active layers were prepared and the field-effect mobility (mu(FET)) and I-on/I-off ratios were determined to be approximately 10(-5) cm(2) V-1 s(-1) and 10(4), respectively. Photovoltaic properties of Py3Si and Py3C were studied in the cells, ITO-PEDOT-PSS-Py3Si or Py3C-PCBM-LiF-Al. Although the power conversion efficiency (PCE) of the cells was only about 0.04%, they showed high open circuit voltages (V-oc) of 0.8-0.9 V. indicating the high potential of this type of compound as a host material.
