Communication: The efficiency of electroluminescent devices is strongly affected by charge carrier mobilities, in that electrons and holes must be able to be quickly transported for high quantum efficiency. Hole mobility data are reported here for a new family of five conjugated copolymers consisting of triarylamines—which are known to possess high time‐of‐flight (TOF) hole mobilities—combined with fluorenes via a Suzuki coupling reaction. All five display high room‐temperature TOF hole mobilities, while one, “TFB“, has the highest yet reported for a π‐conjugated polymer.
