Luminescent metal–organic frameworks (LMOFs) have received considerable attention in recent years because of their enormous potential for a broad range of applications in chemical sensing, energy-efficient lighting, bioimaging, and related fields. Benefiting from their tunable crystal structures, compositions, and porosity, significant progress has been made in developing LMOFs with high luminescence quantum efficiency. In this Perspective, we highlight two recently developed strategies that have been successful in designing LMOFs that are made of chromophoric ligands or that encapsulate emissive guest species. These LMOFs offer the highest photoluminescence performance and most flexibility in tuning emission energy and colors. We also discuss the main challenges as well as new opportunities for the future development of LMOFs.

功能化发光金属有机框架以增强光致发光

发光金属有机框架（LMOF）由于在化学传感，节能照明，生物成像及相关领域的广泛应用具有巨大潜力，因此近年来受到了相当大的关注。得益于其可调谐的晶体结构，组成和孔隙率，在开发具有高发光量子效率的LMOF方面取得了重大进展。在本《观点》中，我们重点介绍了两种最近开发的策略，它们已成功设计出由发色配体制成或封装了发光客体的LMOF。这些LMOF在调整发射能量和颜色方面提供了最高的光致发光性能和最大的灵活性。我们还将讨论LMOF未来发展的主要挑战以及新机遇。
