Smart luminescent materials have recently received significant attention for applications in sensing, optical displays, biological imaging, and therapy. Construction of host-guest self-assembled structures has been an effective way to achieve such luminescent systems. Here, recent advances in layered double hydroxides (LDHs)-based smart luminescence and the tuning of their excited states are reviewed. We introduce the relationship between the structures and luminescent performance of the LDHs’ host-guest materials and their sensor properties. Then, we focus on the tuning of singlet and/or triplet excited states of the LDHs-based luminescent materials. Finally, we briefly review new host-guest fluorescent and long-lived phosphorescent materials with stimuli-responsive behavior.

智能发光材料最近在传感、光学显示、生物成像和治疗方面的应用受到了极大的关注。构建主客体自组装结构是实现此类发光系统的有效方法。本文综述了基于层状双氢氧化物 (LDH) 的智能发光及其激发态调节的最新进展。我们介绍了LDHs的主客体材料的结构和发光性能与其传感器特性之间的关系。然后，我们专注于调整基于 LDHs 的发光材料的单线态和/或三线态激发态。最后，我们简要回顾了具有刺激响应行为的新型主客体荧光和长寿命磷光材料。
