英文摘要	Atmospheric moisture is a sustainable clean water source that can solve the shortage of fresh water in arid areas. Herein a 2D covalent organic framework (COF-ok) was reported as a promising porous sorbent for solar-driven atmospheric water harvesting. COF-ok with ortho-ketoenamine linkage was extremely stable in harsh environment, including in boiling water, strong acids and bases. Because of the balanced hydrophilic and hydrophobic sites in channels, COF-ok showed a high water uptake of 0.33 g g(-1) at a low relative humidity of 34 % featuring a characteristic S-shaped water sorption isotherm with low regeneration temperature (similar to 45 degrees C) and excellent cyclic stability. A laboratory-scale water harvesting system could collect water of 161 g kg(-1) under sunlight.
