Two‐dimensional (2D) nanomaterials, such as graphene and transition metal chalcogenides, show many interesting dimension‐related materials properties. Inspired by the development of 2D inorganic nanomaterials, single‐layered covalent organic frameworks (sCOFs), featuring atom‐thick sheets and crystalline extended organic structures with covalently bonded building blocks, have attracted great attention in recent years. With their unique graphene‐like topological structure and the merit of structural diversity, sCOFs promise to possess novel and designable properties. However, the synthesis of sCOFs with well‐defined structures remains a great challenge. Herein, the recent development of the bottom‐up synthesis methods of 2D sCOFs, such as thermodynamic equilibrium control methods, growth‐kinetics control methods, and surface‐assisted covalent polymerization methods, are reviewed. Finally, some of the critical properties and application prospects of these materials are outlined.
