Light-emitting electrochemical cells are the future generation of display and solid state lighting sources.. Compared to conventional solid state lighting device such as organic light-emitting diode (OLED), (LECs) possess simple device architecture and air stable electrodes makes LECs more impressive. Mainly LECs are two types, p-LECS and Ir-ITMCs. Polymer LECs are tri-component blend containing emitting polymer, an ion-conducting polymer and an inorganic salt. Currently much research has been focused on cationic iridium complexes due to the phosphorescent, color tuning and an ionic nature of Ir-ITMCs. Recently non-ionic small molecule light-emitting electrochemical cell containing the device structure as same as the p-LEC were reported by Tang et al.. The molecule which is an ionic apart from Ir-ITMCs have great attentions. We report LECs based on an ionic fluorene derivatives as an active component.
