摘　　要：有机电致发光材料是有机电子学和光电信息功能材料领域的研究热点之一,在有机π共轭体系中引入杂原子是一种有效调节材料光电性能的手段。磷原子既可以通过其d轨道与π共轭体系间的σ-π相互作用来改变材料的电子结构,又具有很好的可修饰性,如被氧化、硫化或与金属配位等,从而能有效地调控材料的光电性能。因此,磷原子的引入为有机光电功能材料的分子结构设计和光电性能改善等方面的研究提供了广阔的空间,近年来得到了研究者较多的关注。本文根据引入磷原子的不同方式,综述了磷杂环戊二烯、二噻吩并磷杂环戊二烯、磷芴以及磷杂聚苯撑乙烯等材料的结构特点和在有机电致发光材料方面的研究现状,展望了含磷有机电致发光材料的应用前景和发展趋势。A great deal of attention has been focused on the clectroluminescent materials due to their great potentials in organic light-emitting diodes （OLEDs）. The incorporation of heteroatoms into π-conjugated systems is an effective method to modify the properties of organic electroluminescent materials. Phosphorus atom not only possesses d orbit for σ-π interaction, but also allows chemical modifications in diverse ways, such as oxidation, sulfuration and metal-coordination to fine-tune the properties. The rapid development of phosphorus-containing ^- conjugated materials greatly broadens the molecular structure design and the optoelectronic property improvement of organic electroluminescent materials. In this review, various phosphorus-containing π-conjugated materials were summarized and discussed according to the different incorporation modes of the phosphorus atoms, including phosphole, dithienophosphole, phosphalfluorene, and phosphorus substituted polyphenylene vinylene, etc. The progress of phosphorus-containing electroluminescent materials were summarized and their future development was prospected.
