    Covalent Organic Frameworks (COFs) are a class of crystalline porous polymer that enables the use of pure organic building blocks to build extended polygon architectures and latticed polymer backbones. Recent progress has greatly enhanced the flexibility and accessibility of chemistry to design structures as well as functions, showcasing the emerging of this new field. From a chemistry perspective, COFs have the possibility of engineering predesigned materials with tailor-made structural hierarchy. Importantly, COFs offer an irreplaceable platform for exploring multi-functional materials and molecular systems. In this lecture, I will report our discovery of COFs and their chemistry to structures and functions, by focusing on their inherent two-dimensional frameworks and one-dimensional channels.
