Light-emitting electrochemical cells are the future generation of flat-panel displays and solid state lighting sources. 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. 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 designed and synthesized an ionic fluorene derivative containing naphthalene units in multi-step synthetic procedure having strong luminescence and good charge transporting capabilities. A complete structural, photophysical, electrochemical and electroluminescent properties were investigated. The LEC device exhibits deep blue light- emissions centered at 424 nm with CIE coordinates of (0.17, 0.17). |
