摘要：
Bisphenylene-spirobifluorene compounds, a method for synthesizing the same, and EL material and device having the same. The bisphenylene-spirobifluorene compound is defined by the following formula: wherein R1 and R2 are identical or different and are independently a straight-chain or branched alkyl group having from 1 to 22 carbon atoms, X1 and X2 independently contains one or more elements selected from the group consisting of C, O, N, S, Si and Ge, and m and n are integers from 1 to 4.
