Light-emitting electrochemical cells(LECs) are the future generation of flat-panel displays. Solid state lighting sources LECs possess simple device architecture and air stable electrodes makes LECs more impressive.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 fluorene derivative in multi-step synthetic procedure having strong luminescence and good charge transporting capabilities. A complete structural, photophysical, electrochemical properties were investigated. Deep blue light- emissions were achieved by applying the target compound in a LEC device |
