N2 - Alternating conjugated polymers of ethylenedioxythiophene and fluorene are prepared using three different synthetic methods to investigate the effects of these synthetic methods on the purity, field-effect transistor (FET) performance, and organic photovoltaic (OPV) performance of the polymer. In this study, microwave-assisted direct arylation polycondensation is used to obtain a high-purity, high-molecular-weight (147 kDa) polymer. This pure polymer exhibits a high FET hole mobility of 1.2 × 10-3 cm2 V -1 s-1 and high OPV performance with a power conversion efficiency of 4%, even though the polymer forms an amorphous film, which absorbs in a limited region of the spectrum. Field-effect transistor and organic photovoltaic performances strongly depend on the synthetic methods of a polymer owing to different purity and molecular weight. A high-purity, high-molecular-weight polymer exhibits a high FET hole mobility of 1.2 × 10-3 cm2 V-1 s-1 and high OPV performance with a power conversion efficiency of 4%, even though the polymer forms an amorphous film, which absorbed in a limited region of the spectrum.
