We report herein an efficient, fast, and simple synthesis of an imine‐based covalent organic framework (COF) at room temperature (hereafter, RT‐COF‐1). RT‐COF‐1 shows a layered hexagonal structure exhibiting channels, is robust, and is porous to N2 and CO2. The room‐temperature synthesis has enabled us to fabricate and position low‐cost micro‐ and submicropatterns of RT‐COF‐1 on several surfaces, including solid SiO2 substrates and flexible acetate paper, by using lithographically controlled wetting and conventional ink‐jet printing. Printed crystals: An efficient, fast and simple synthesis of an imine‐based porous covalent organic framework (COF) at room temperature is reported. The room‐temperature synthesis enables fabricating micro‐ and submicropatterns of this COF on a variety of surfaces by ink‐jet printing and wet lithographically techniques.
