Reticular chemistry guided single-linker constructed pillar-layered metal-organic frameworks an "one-pot" strategy.

In the present work, we report a "two-in-one" strategy to construct single-linker-based pillar-layered metal-organic frameworks (PL-MOFs) guided by reticular chemistry an "one-pot" approach. Two carboxyl groups and one pyridine group are integrated into one molecular skeleton to form bifunctional organic linkers the reaction of pyridine-containing aldehyde and bicarboxylate-containing -phenylenediamine. During the synthesis of organic linkers, two zinc-based PL-MOFs, non-interpenetrated HIAM-3016-op and two-fold interpenetrated HIAM-3017-op, can be simultaneously constructed. The different interpenetrations for these two PL-MOFs can be attributed to the increased length of the pyridine-containing moiety. HIAM-3017-op can be utilized for CrO detection with excellent sensitivity and selectivity. The present work not only provides a novel insight to design and prepare PL-MOFs with specific structures guided by reticular chemistry, but also indicates the universality of the "one-pot" strategy to construct porous materials.
