In the past decades,organic molecules with well-fined π aromatic backbones,applied to the organic light-emitting diodes(OLEDs)display materials,have drawn tremendous attention for their exceptional optoelectronic characteristics[1,2].Fluorene-based compounds possess rigid planar structure in result of good fluorescence properties and high quantum efficiency.They also can improve the thermal stability,shape stability and the stability of carrier mobility when applied in OLEDs[3].Therefore,research of fluorene-based derivation is becoming hot and growing fast in recent years.In this paper,a new type of fluorene-based compound has been synthesized through Suzuki coupling reaction,and characterized by elemental analysis,single-crystal X-ray diffraction,IR spectra and powder single X-ray diffraction.Meanwhile,the spectroscopic properties of the title compound were investigated through UV-Vis absorption and fluorescence spectra.The results showed that the synthetic compound emitted purple fluorescence with an emission peak of 388 nm,under excitation of 273 nm at room temperature.This compound has highly efficient and stable fluorescence property.
