As an emerging class of crystalline materials, covalent organic frameworks (COFs) have drawn numerous attentions owing to their light weight and highly ordered porous structure. Compared with one-dimensional conjugated polymers, conjugated COFs are able to extend the conjugation in two- or even three-dimensional directions, which endows them as promising candidates of light-emitting materials. In this review, the recent progress in photoluminescent COFs will be discussed from the mechanisms to the proposed design strategies and finally to the corresponding applications. Most recent developments (especially from 2019 to now) will be highlighted. Moreover, the summary and perspective of COFs as light-emitting materials will be presented, aiming to provide some guidelines for the development of luminescent COFs.

作为新兴的一类晶体材料，共价有机骨架（COF）由于其轻巧的重量和高度有序的多孔结构而备受关注。与一维共轭聚合物相比，共轭COF能够在二维或什至三维方向上扩展共轭，这使它们成为发光材料的有希望的候选者。在这篇综述中，将从机理到建议的设计策略，再到相应的应用，讨论光致发光COF的最新进展。将重点介绍最新的发展（尤其是从2019年至今）。此外，将介绍COF作为发光材料的概述和观点，旨在为发光COF的开发提供一些指导。
