Abstract :

Light-emitting electrochemical cells have becoming attractive in thin-film applications. Compared to conventional solid state lighting device such as Organic Light-Emitting Diode (OLED), Light-Emitting Electrochemical Cell (LECs) possess simple device architecture and air stable electrodes makes LECs more impressive. Mainly LECs are two types, p-LECS and Ir-ITMCs. Polymer lightemitting electrochemical cells 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. However, the source and expensive nature of iridium demands new emitters in LECs. 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 has great attentions. We designed and synthesized an ionic phenothiazine derivatives in multi-step synthetic procedure for light-emitting electrochemical cells. A complete structural, photo physical, electrochemical and electroluminescent properties were investigated. The emissions color-tuning of compounds, were covering blue and region achieved by applying the target compound in a LEC device.
