From a chemical standpoint, the establishment of synthetic protocols adapted to control the generation and growth of correlated disorder is crucial to consider defect engineering a practicable route towards adjusting framework function. By using UiO-66 as experimental platform, we systematically explored the framework chemical space of the corresponding defective materials. Periodic disorder arising from controlled generation and growth of missing cluster vacancies can be chemically controlled by the relative concentration of linker and modulator, which has been used to isolate a crystallographically pure “disordered” reo phase. Cs-corrected scanning transmission electron microscopy is used to proof the coexistence of correlated domains of missing linker and cluster vacancies, whose relative sizes are fixed by the linker concentration. The relative distribution of correlated disorder in the porosity and catalytic activity of the material reveals that, contrarily to the common belief, surpassing a certain defect concentration threshold can have a detrimental effect. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 14.7 2023 MULTIDISCIPLINARY SCIENCES 8 / 134 = 0.06 2023 Q1 T1 4.887 2023 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2023 Q1 Physics and Astronomy (miscellaneous) 2023 Q1 Chemistry (miscellaneous) 2023 Q1 24.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez-Giménez, Sonia Rubio-Gaspar, Ana Gómez-Oliveira, Eloy Castells-Gil, Javier Dong, Zhuoya Mayoral, Álvaro Universidad de Zaragoza (orcid)0000-0002-5229-2717 Almora-Barrios, Neyvis M.
