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。
Organic electroluminescent materials are one of the hot topics in the field of organic electronics and optoelectronic information functional materials. The introduction of heteroatoms in organic π-conjugated systems is a means of effectively adjusting the optoelectronic properties of materials. Phosphorus atoms can change the electronic structure of the material through the σ-π interaction between the d orbit and the π-conjugated system, and have good modifiability such as oxidation, sulfidation or metal coordination, Effectively control the photoelectric properties of materials. Therefore, the introduction of phosphorus atoms provides a great space for the research on the molecular structure and optoelectronic properties of organic optoelectronic functional materials. In recent years, researchers have received more attention. In this paper, according to different ways of introducing phosphorus atoms, the structural characteristics of materials such as phosphacyclopentadiene, dithienophospheclopentadiene, fluorene and phosphaphenylene polyphenylene vinylene are summarized and their applications in organic electroluminescent materials The prospect and development trend of phosphorus-containing organic electroluminescent materials are prospected.
