Polymer light‐emitting electrochemical cells with long operating lifetimes (see figure) are reported. The ions inside the luminescent semiconducting polymer are spatially redistributed by applying a voltage at a temperature above the melting point of the ionic liquid. These ionic‐liquid‐based light‐emitting electrochemical cells also exhibit excellent current‐rectification diode properties, a single‐phase active layer, and short response times.
