A facile new protocol for the synthesis of iodinated derivatives of fluorinated benzothiadiazoles is demonstrated for the production of p-type semiconducting materials. The newly synthesized small-molecule compounds bis[TPA-diTh]-MonoF-BT and bis[TPA-diTh]-DiF-BT exhibited a power conversion efficiency of 2.95 % and a high open-circuit voltage of 0.85 V in solution-processed small-molecule organic solar cells. A facile new protocol was developed for synthesis of iodinated derivatives of fluorinated benzothiadiazoles as precursors for fluorine-substituted benzothiadiazole-based organic semiconductors 2 and 3, which exhibit enhanced intramolecular charge transfer compared to unfluorinated analogue 1 and hence improved photovoltaic performance in small-molecule organic solar cells (see figure).
