    • PURPOSE: A spirobifluorene-based compound and a preparation method thereof are provided to improve luminous efficiency and processability due to good solubility in organic solvent. The compound is suitably applied as a blue light-emitting element with improved adhesiveness to a substrate, stability and service life. An organic light-emitting device using the novel spirobifluorene compound is also provided to improve the luminous efficiency, brightness and the purity and stability of colors. CONSTITUTION: The spirobifluorene-based compound has a structure of formula 1, wherein each R1 and R2 is a hydrogen atom, an alkoxy group having C1-20 or an alkyl group having C1-20; X is a fluorine atom, a cyano group or an amine group (-NRR, in which R is a hydrogen atom or an alkyl group having C1-20). The light-emitting device comprises a cathode, an anode and a light-emitting layer containing the spirobifluorene-based compound between the cathode and the anode.
