Side chains in different amino acid derivatives and anions (Cl<sup>–</sup>, Br<sup>–</sup>) have been identified to play an important role in structural diversity (from porous to nonporous) as well as physical properties. These metal–organic frameworks (MOFs) exhibit a distinct water adsorption nature and capacity, e.g., high adsorption at low partial pressure based on architectural diversities.
