Based on silafluorene core, the liquid crystal silafluorene and spiro-silicon bridged silafluorene compounds were synthesized. Apart from higher thermal stability, the obtained compounds containing liquid crystal units demonstrated liquid crystal behavior and fluorescent properties with higher solid fluorescent quantum yield. The spiro-silicon bridged compound displayed good solubility, which led to easy processing. Besides, it exhibited easy preparation and higher emissive fluorescent properties.
