Metal-organic frameworks (MOFs) are novel porous materials which have great potential in various fields such as catalysis and biomedicine. One main goal in this field is to create MOFs with hierarchical pores, which can not only improve mass transfer within frameworks, but also allow for encapsulating large guest molecules. Here we report a facile photolytic strategy to introduce mesopores into microporous MOFs by eliminating photolabile ligands in multivariate MOFs with laser treatment. To prove our concept, we perform photolysis on multivariate UiO-66 mixed with photolabile ligands, which can be eliminated selectively under laser, and the generation of mesopores are confirmed by N2 isotherms, IR, NMR and TGA. This strategy features advantages in accuracy, efficiency and feasibility in multipe MOFs, shedding a light on programmable design of complicated cooperative MOF system.
