英文摘要：

A novel A-D-A blue emitter containing fluorene, phenanthroimidazole and acetylene group moieties was synthesized and characterized, named as FI. Its photophysical and photochemical properties were systematically in-vestigated. The results showed FI exhibits excellent solubility, fluorescence, thermal stability and film formation, which is a good candidate for the fabrication of solution-processable organic light-emitting diodes. A non-doped blue organic light-emitting diode based on FI as the emitter showed the maximum luminance efficiency of 1. 52 cd·A-1 , and the maximum power efficiency could reach 0. 63 lm·W-1 .
