3D Covalent Organic Frameworks

Since the pioneering work by Yaghi and co-workers in 2007, three-dimensional covalent organic frameworks (3D COFs) have aroused worldwide interest due to their large surface areas, abundant functional moieties, and promising chemical stabilities. With multifarious building blocks and functional approaches, 3D COFs are explored in gas uptake and separation, solvent extraction, heterogeneous catalysis, batteries, chemical sensing, and so on. This chapter will discuss the current development of 3D COFs from structure factors, functional approaches, and potential applications.
