Functionalization of organic semiconductors with fluorine atoms and fluorine-containing groups can give rise to a wide variety of properties, for example, increase the rate of electron transport, induce harvesting of non-emissive triplet excitons through thermally activated delayed fluorescence (TADF) or room temperature phosphorescence (RTP), improve photoluminescence quantum yield (PLQY) by forming multiple intra- and intermolecular interactions, and increase solution- processabitily of the compounds, therefore, lowering the cost of device fabrication. Diverse synthetic approaches have been implemented to afford fluorinated organic semiconductors. In this review, we discuss some of the recent and most interesting organic semiconductors with C–F and C–CF3 bonds as well as their application.
