Cucurbit[n]urils (Q[n]s or CB[n]s), as a classical of artificial organic macrocyclic hosts, were found to have excellent advantages in the fabricating of tunable and smart organic luminescent materials in aqueous media and the solid state with high emitting efficiency under the rigid pumpkin-shaped structure-derived macrocyclic-confinement effect in recent years. This review aims to give a systematically up-to-date overview of the Q[n]-based supramolecular organic luminescent emissions from the confined spaces triggered host–guest complexes, including the assembly fashions and the mechanisms of the macrocycle-based luminescent complexes, as well as their applications. Finally, challenges and outlook are provided. Since this class of Q[n]-based supramolecular organic luminescent emissions, which have essentially derived from the cavity-dependent confinement effect and the resulting assembly fashions, emerged only a few years ago, we hope this review will provide valuable information for the further development of macrocycle-based light-emitting materials and other related research fields.

葫芦脲大环约束超分子有机发光的组装和应用

葫芦[ n ]urils（Q[ n ]s或CB[ n ]s）作为一种经典的人造有机大环主体，被发现在水介质和固体中制备可调谐和智能有机发光材料方面具有优异的优势。近年来在刚性南瓜形结构衍生的大环约束效应下具有高发射效率的状态。本综述旨在对 Q[ n] 基超分子有机发光从受限空间发射触发主客体复合物，包括组装方式和基于大环的发光复合物的机理，以及它们的应用。最后，提出了挑战和展望。由于这类基于 Q[ n ] 的超分子有机发光发射，本质上来源于腔依赖的限制效应和由此产生的组装方式，仅在几年前出现，我们希望这篇综述能为进一步的研究提供有价值的信息。开发大环基发光材料等相关研究领域。
