Abstract
. Furthermore, organic photovoltaic cells (OPVs) based on PTNT1-F showed high power conversion efficiencies of up to 17.4% when combined with a nonfullerene acceptor. This work provides an efficient method for the thienannulation of electron-deficient rings to access thiophene-fused A building units and shows the great promise of TNT as a building unit for high-performance π-conjugated polymers for organic electronic devices.
