摘　　要：苯并噻吩及其衍生物在光电材料领域的应用受到广泛关注.本研究以苯并噻吩为原料,与NBS发生卤代反应得到2,3-二溴苯并噻吩,然后与正丁基锂、二苯基氯化膦反应生成苯并噻吩双膦配体2,3-二(二苯基膦基)苯并噻吩.用核磁共振谱(^(1)H、^(13)C、^(31)P NMR)、傅里叶变换红外光谱(FT-IR)、高分辨电喷雾质谱(HRMS-ESI)等对目标化合物进行表征,确证了结构,为后续合成苯并噻吩金属配合物发光材料提供一种新的配体.该化合物目前鲜见报道.Benzothiophene and its derivatives have attracted great attention attributed to their application as photoelectric materials.In our research,benzothiophene was used as raw material to react with NBS to produce 2,3-dibromobenzothiophene,then it was continued to react with n-butyllithium and diphenylphosphine chloride to form benzothiophenyl diphophines ligand 2,3-bis(diphenylphosphino)benzo[b]thiophene.The structure of the title compound was characterized and confirmed by NMR(^(1)H,^(13)C and ^(31)P),FT-IR,HRMS-ESI spectra.It provided a precursor for synthesis of luminescent benzothiophene metal complexes in the further step.As far as we know,this compound has not been reported.
