| Research Abstract |
We attempted to dope carriers to organic semiconductors and make single crystals with sufficient sizes and studied its thermoelectric properties. We investigated the melting behavior of copper phthalocyanine (CuPc) to anthraquinone (AQ), which are both solid at room temperature. We attempted to grow the single crystal of CuPc by evaporating the solvent AQ and obtained mm-sized single crystals. We doped FeCl3 to CuPc by mixing the dopant to the solution. XPS and near infrared spectroscopy revealed that the charge transfer extent is dependent on the molar fraction of the dopant. The electric conductivity and Seebeck coefficient both increased upon doping.
