金属有机骨架(M0F)以其可调结构和多孔性而众所周知。许多研究表明,它们有希望用于各种重要的应用,对于这些应用,它们的性能可以通过将功能物种(例如发光客体分子)封装在框架内来进一步增强。尽管许多MOF是发光的,但很少有发射白色光的,并且它们的量子产率通常较低。在这里,我们报告了一种策略,以实现有效的白光发射封装铱配合物的MOF腔。制备了一种介孔蓝光发射MOF作为主体,以封装发黄光的铱配合物[Ir(ppy)2(bpy)]+。所得到的复合材料发射明亮的白色光,具有良好的颜色质量(例如,国际照明委员会坐标,显色指数和相关色温分别为(0.31,0.33),84.5和5409 K),以及高达115 °C的高量子产率。这一策略可能为开发高性能节能固态照明材料开辟新的前景。 虽然许多金属有机框架是发光的,但很少有能够发射白光的。在这里,作者将发黄色光的客体分子掺入发蓝色光的金属有机框架的空腔中,并调整组合物以发射具有相对较高量子产率的白色光。
Metal–organic frameworks (MOFs) are well known for their tunable structure and porosity. Many studies have shown they are promising for various important applications, for which their performance can be further enhanced by encapsulating functional species, such as luminescent guest molecules, within the frameworks. Although numerous MOFs are luminescent, very few emit white light and their quantum yield is usually low. Here we report a strategy to achieve efficient white-light emission by encapsulating an iridium complex in the MOF cavity. A mesoporous blue-emitting MOF is prepared as host to encapsulate a yellow-emitting iridium complex, [Ir(ppy)2(bpy)]+. The resultant composites emit bright white light with good colour quality (for example, Commission International de I’Eclairage coordinates, colour-rendering index and correlated colour temperature of (0.31, 0.33), 84.5 and 5409 K, respectively), and high quantum yield up to 115 °C. This strategy may open new perspectives for developing high-performance energy-saving solid-state lighting materials. Although many metal–organic frameworks are luminescent, few are capable of white-light emission. Here, the authors incorporate a yellow-emitting guest molecule into the cavities of a blue-emitting metal–organic framework, and tune the composition to emit white light with relatively high quantum yield.
