Recent Progress in Metal-Organic Frameworks for White-Light Emission

金属有机框架化合物(MOFs)是一类备受关注的多功能杂化材料,结构的多样性使其表现出各种发光性能。尤其是环境友好、使用寿命长、效率高的白光MOFs材料的出现为新型发光MOFs的设计和制备提供了契机。我们旨在总结白光MOFs的最新研究进展,着重对其合成方法及应用进行综述,主要包括镧系离子共掺杂、镧系元素封装或有机分子捕获等获得可调控的白光MOFs的方法及其在温度、分子和金属离子传感器等领域的潜在应用。同时,针对白光MOFs材料面临的挑战和未来发展也进行了梳理。以期引起设计和构建新型发光MOFs的研究人员的关注与兴趣。

Metal-organic frameworks(MOFs)are a high-profile sort of multifunctional hybrid materials and display various luminescent behaviors due to the diversities of their architectures.Extraordinarily,the emergence of white-light-emitting(WLE)MOFs offers golden opportunities for designing and constructing new luminescent MOFs materials owing to their environmental friendliness,long service lives and high efficiencies.In this manuscript,we focus on recent developments of the WLE MOFs with particular emphases on their synthetic methods and properties,which mainly include co-doping of Ln3+in multifarious MOFs materials,lanthanide encapsulation or organic molecules capture in MOF pores to obtain tunable WLE MOFs,and several potential sensing applications including temperature,molecular and metal ions sensors.In addition,imminent challenges and future developments of WLE MOFs materials are both proposed.This review may arouse the interest of researchers who will design and construct new luminescent MOFs.
