Even though organic light-emitting device (OLED) technology has evolved to a point where it is now an important competitor to liquid crystal displays (LCDs), further scientific efforts devoted to the design, engineering and fabrication of OLEDs are required for complete commercialization of this technology. Along these lines, the present work reviews the essentials of OLED technology putting special focus on the general working principle of single and multilayer OLEDs, fluorescent and phosphorescent emitter materials as well as transfer processes in host materials doped with phosphorescent dyes. Moreover, as a prototypical example of phosphorescent emitter materials, a brief discussion of homo- and heteroleptic iridium(III) complexes is enclosed concentrating on their synthesis, photophysical properties and approaches for realizing iridium based phosphorescent polymers.
尽管有机发光二极管(OLED)技术已经发展到足以成为液晶显示器(LCD)的重要竞争对手的地步,但为了实现这项技术的完全商业化,还需要在设计、工程和制造方面做出进一步的科学努力。有鉴于此,本工作综述了 OLED 技术的要点,特别关注单层和多层 OLED 的一般工作原理、荧光和磷光发射器材料以及掺杂磷光染料的主体材料中的传输过程。此外,作为磷光发射器材料的典型示例,简要讨论了同型和异型铱(III)配合物,重点关注它们的合成、光物理性质以及实现基于铱的磷光聚合物的方法。
