In order to improve power conversion efficiency by changing the molecular orientation, we designed and synthesized a new thiadiazole-based acceptor, FOBTzE, based on the vinylene-bridged alkoxyfluorobenzothiadiazole scaffold. We also synthesized FOBTzE-based p-type semiconducting polymers and investigated their fundamental physicochemical and photovoltaic properties.
