      abstract = {Covalent organic frameworks (COFs) have emerged as  promising atmospheric water harvesters, offering a  potential solution to the pressing global issue of water  scarcity, which threatens millions of lives worldwide. This  study presents a series of 2D COFs, including HCOF-3,  HCOF-2, and a newly developed structure named COF-309,  designed for optimized water harvesting performance with a  high working capacity at low relative humidity. To  elucidate their water sorption behavior, we introduce a  hydrophilicity index directly linked to intrinsic  properties, such as the strength and spatial density of  adsorptive sites. This index is mathematically correlated  to the step of water adsorption isotherms. Our correlation  provides a predictive tool that extends to other  microporous COFs and metal–organic frameworks,  significantly enhancing the ability to predict their onset  positions of water adsorption isotherms based on structural  characteristics. This advancement holds the potential to  guide the development of more efficient materials for  atmospheric water harvesting.},
