摘要:

在过去的几十年里, 有机发光二极管(OLED)由于潜在的优势, 在全彩显示领域引起了高度重视. 电致磷光材料因其优异的发光性能, 引起了人们广泛关注. 对于实际应用的平板显示器, 蓝、绿、红三基色是必不可少的. 相对于高效的绿光材料, 红光磷光材料仍然存在色纯度差、效率低和亮度不足等问题, 因此设计合适的红光材料成为具有挑战性的问题. 稠杂环化合物因发光量子效率高、发光颜色可调、平衡电荷注入及迁移等优越性能而广泛应用于红色磷光铱配合物. 本文综述了近几年稠杂环化合物在小分子、树枝状及高分子红色磷光铱配合物中的应用, 阐述了铱配合物分子结构对材料光电性质及器件性能的影响, 最后展望了稠杂环化合物在红光磷光材料中的应用前景.

Abstract:

Organic light-emitting diodes (OLEDs) have attracted considerable attention during the last decade because of the potential advantages associated with their usage in full-color displays. Electroluminescent phosphorescent materials have also enjoyed similar levels of attention because of their excellent luminescent properties. The three primary colors, blue, green, and red, are essential for the practical application of phosphorescent complexes in flat-panel displays. Relative to the efficient green phosphorescent materials, red phosphorescent materials suffer many problems, including poor color purity, low efficiency, and low luminance, and the design of appropriate red colored materials therefore represents a significant challenge. Fused-heterocyclic compounds have been widely used in red phosphorescent iridium(III) complexes because of their high quantum efficiency, color adjustability, and balanced charge injection and migration. This review summarizes the development and application of fused-heterocyclic compounds in recent years in small molecule, dendrimer and polymeric red phosphorescent iridium(III) complexes. The influence of the molecular structures of iridium(III) complexes on the optical and electrical properties and device performances has also been described. Finally, a discussion of the prospect of developing fused-heterocyclic compounds in the red phosphorescent materials has also been provided.

Key words: Phosphorescent material, Iridium(III) complexes, Fused-heterocyclic compound, Dendrimer, Polymer
