Physical Properties, Charge Carrier Mobility, and Photovoltaic Performance of Dendritic Oligothiophene Bearing Naphthalene Bis(dicarboximide) Groups

Dendritic oligothiophene having naphthalene bis(dicarboximide) (NDI) was synthesized, and its physical properties were investigated by ultraviolet–visible (UV–vis) spectroscopy and cyclic voltammetry. The charge carrier mobility measurements by organic field-effect transistor devices and flash-photolysis time-resolved microwave conductivity measurements revealed p-channel behavior. The photovoltaic performance of the dendritic oligothiophene–NDI dyad with PCBM exhibited a power conversion efficiency of 0.14%.
