As a result of their outstanding attributes, organic light-emitting diodes (OLEDs) and white organic light-emitting diodes (WOLEDs) have been recognized in recent years as the most promising candidates for future flat-panel display technologies and next generation solid-state energy-saving lighting sources. New advancements in the area of high performance triplet emitters become vital for realizing more practical applications. In this regard, several critical issues must be carefully identified and addressed, and these include the ways to enhance device efficiency and suppress efficiency roll-off, to achieve versatile color tuning and simple device manufacture, as well as to obtain high-quality white light from WOLEDs. It has been shown that some functionalized phosphorescent Ir(III) and Pt(II) ppy-type cyclometalated complexes (ppy = 2-phenylpyridine) possess unique features that are suitable for solving these difficult and challenging tasks. In this Focus Review, we will highlight the recent design tactics adopted for these functional metallophosphors and the critical roles they may play in developing more realistic devices.
近年来,有机发光二极管(OLED)和白色有机发光二极管(WOLED)因其出色的性能而被认为是未来平板显示技术和下一代固态节能光源最有前途的候选者。在高性能三重态发射器领域的新进展对于实现更实际的应用变得至关重要。在这方面,必须仔细识别和解决几个关键问题,包括提高器件效率和抑制效率滚降的方法,实现多功能的颜色调谐和简单的器件制造,以及从 WOLED 获得高质量的白光。已经表明,一些功能化的磷光 Ir(III)和 Pt(II)ppy 型环金属化配合物(ppy = 2-苯基吡啶)具有独特的特性,适合解决这些困难和具有挑战性的任务。在本重点综述中,我们将重点介绍这些功能金属磷光体所采用的最新设计策略,以及它们在开发更实际的器件方面可能发挥的关键作用。
