abstract = "We will present a breakthrough in the stability of the simplest light-emitting electrochemical cells (LECs). The main drawback of these molecular devices limiting their practical use are their short lifetimes, which range from several minutes to a few days due to intrinsic instabilities of the ionic transition-metal complex (iTMC's). By using an ionic iridium(III) complex conveniently designed to form a supramolecularly-caged structure, we show that the lifetime of LECs can be increased to more than 3000 hours at an average luminance of 200 cd m-2 while operating at a bias of only 3 volts. In order to reduce the turn-on time to a few minutes small amount of ionic liquid (IL) were added and short pulses of higher-voltage were applied at the start.",
