Multivariate Hydrogen-Bonded Organic Frameworks for Optimum Atmospheric Water Harvesting.

ABSTRACT: Hydrogen-bonded organic frameworks (HOFs) offer atomic-precision platforms for probing water adsorption, yet monotonic building units often fail to meet the multifaceted demands of atmospheric water harvesting (AWH). In this study, a multivariate (MTV) strategy is employed to tune adsorption onset, work capacity, and cycling stability in HOFs. Introducing amino groups in controlled ratios creates a balance between hydrophilic sites and dynamic confinement within ordered frameworks. Specifically, the parent HOF, PFC-76, was constructed from the organic linker [1,1':4',1″-terphenyl]-3,3″,5,5″-tetracarboxylic acid (TPTCA), which assembles into 2D honeycomb networks via carboxylic acid dimer synthons. Functionalizing TPTCA with amino groups modulates the framework's packing and dynamic behavio
