Résumé
Starting from 5‐hydroxyisophthalic acid (not shown), in situ nitration leads to different nitrated linker molecules that selectively react with Ga3+ or Al3+ ions to Ga‐MIL‐53 and Al‐CAU‐10 type frameworks, respectively. The pale blue and orange light path represents the crystallization of the respective MOF. More information can be found in the Full Paper by N. Stock et al. (DOI: 10.1002/chem.202100373).
