摘　　要：含有N^P^N配体的高效发光金属配合物应用于OLED的研究引起了广泛关注.以3,5-二甲基吡唑为原料,与1-氟-2-溴苯发生亲核取代反应后,再依次与正丁基锂、二氯苯基膦反应生成目标化合物二[2-(3,5-二甲基吡唑基)苯基]苯基膦.采用核磁共振谱((1)^H、(13)^C、(31)^P NMR)、傅里叶变换红外光谱(FT-IR)、高分辨质谱(HRMS)等对目标化合物进行了结构表征,确证了结构.为后续合成高效发光金属配合物提供了一种新的配体.该化合物目前鲜有报道.Highly emissive metal complexes with N^P^N ligand applied in OLEDs have attracted great attention.In this paper,3,5-dimethylpyrazole was used as raw material and reacted with 1-bromo-2-fluorobenzene by nucleophilic substitution reaction,and then reacted with n-butyl lithium and dichlorophenylphosphine to generate the title compound di[2-(3,5-dimethylpyrazolyl)phenyl]phenylphosphine.The structure of the title compound was characterized and confirmed by NMR((1)^H,(13)^C and(31)^P),FT-IR,HRMS spectra.It provide a new ligand for synthesis of high efficiency photoluminescent metal complexes in the further step.The compound has been reported rarely so far.
