Light-emitting electrochemical cells (LECs) operate via the accumulation of ionic species provided by the electrolyte at the electrodes. It is shown here that different conjugated polymer/electrolyte phase-separation processes (see Figure), in combination with the complexation tendencies of the ionic species and the ionic transport numbers, influence the performance of LECs. This opens up new strategies for tuning the optoelectronic properties of ion-supported organic electronic devices.
