Abstract
We have developed dendritic oligothiophenes bearing perylene bis(dicarboximide) units and investigated the photophysical and electrochemical properties, photovoltaic performance, and charge carrier mobility. The extended conjugation of the central oligothiophene unit led to an improved performance of the thin-film photovoltaic device and charge carrier mobility of 1.3 × 10−2 cm2 V−1 s−1 estimated by the combination of time-resolved microwave conductivity (TRMC) and transient absorption spectroscopy (TAS) measurements.
