Abstract
A method of water uptake is provided. The method includes contacting a hydrogen-bonded organic framework (HOF) with water to form a mixture where the HOF comprises hydrogen bonded units of trimesic acid and guanazole. The HOF has a sheet structure, where the sheets form an intercrossed macroporous network with pores on a surface. The HOF absorbs at least a portion of the water in the mixture.
