Communication: The performance of molecular‐based devices canb e improved by increasing the carrier mobility of the organic semiconductor. A method for achieving up to a 700‐fold increase in the carrier mobility, which involves the electrochemical inclusion of metal ions (silver and copper) into the semiconducting organic material, is reported. The effect is thought to be the result of the metal ions acting as bridges between neighboring polymer chains thus increasing the interchain carrier hopping rate.
