Modification by Fluorine as Efficient Tool for the Enhancement of the Performance of Organic Electroactive Compounds – A Review
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.
