Heterogeneous catalysts offer a cyclable platform for exploring efficient transformation systems, and their promising applications underpin a broad research interest. Covalent organic frameworks (COFs) are a class of crystalline porous networks that can integrate organic units into ordered skeletons and pores, offering an insoluble and robust platform for exploring heterogeneous catalysts. In this Outlook, we describe a conceptual scheme for designing catalytic COFs to promote various transformations. We summarize the general strategy for designing COFs to construct tailor-made skeletons and pores by emphasizing their structural uniqueness. We introduce different approaches to develop catalytic functions by sampling COFs into four regimes, i.e., skeletons, walls, pores, and systematically organized systems. We scrutinize their catalytic features and elucidate interplays with electrons, holes, and molecules by highlighting the key role of interface design in exploring catalytic COFs. We further envisage the key issues to be challenged, future research directions, and perspectives to show a full picture of designer heterogeneous catalysis based on COFs.

异构催化的共价有机框架：原理，现状和挑战。

非均相催化剂为探索高效的转化体系提供了可循环的平台，其有前途的应用奠定了广泛的研究兴趣。共价有机骨架（COF）是一类晶体多孔网络，可以将有机单元整合到有序的骨架和孔中，从而为探索多相催化剂提供了不溶且坚固的平台。在本《展望》中，我们描述了设计催化COF来促进各种转化的概念方案。我们通过强调结构独特性，总结了设计COF来构造量身定制的骨架和孔的一般策略。我们通过将COF采样到四个区域（骨架，墙壁，孔和系统地组织的系统）中来介绍开发催化功能的不同方法。我们通过强调界面设计在探索催化COF中的关键作用，研究了它们的催化特性并阐明了与电子，空穴和分子的相互作用。我们进一步设想了要挑战的关键问题，未来的研究方向和观点，以展示基于COF的设计师多相催化的全貌。
