Abstract:
In order to gain improved insight into the fundamental mode of operation of light-emitting electrochemical cells (LECs), LECs were prepared from a solid-state electrolyte, consisting of the cryptand (Kryptofix® 222, [2.2.2] cryptand) and lithium triflate, and a blue emitting low-Stokes-shift poly(para-phenylene). The devices reveal LEC-like characteristics, however, their evolution appear on a longer time scale, which is a consequence of reduced cation conductivity of the [2.2.2] cryptands compared to commonly used ion conductors and decelerated electrochemical n doping near the cathode. It is possible to study the location and direction of the emission zone shift during device operation.
