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.
在本工作中，我们报道了一种“二合一”策略，即在网状化学指导下采用“一锅法”构建基于单连接体的柱状层状金属有机框架（PL-MOFs）。将两个羧基和一个吡啶基整合到一个分子骨架中，通过含吡啶醛与含双羧酸盐的对苯二胺反应形成双功能有机连接体。在有机连接体的合成过程中，可同时构建两种锌基PL-MOFs，即非互穿的HIAM-3016-op和二重互穿的HIAM-3017-op。这两种PL-MOFs不同的互穿情况可归因于含吡啶部分长度的增加。HIAM-3017-op可用于CrO检测，具有出色的灵敏度和选择性。本工作不仅为在网状化学指导下设计和制备具有特定结构的PL-MOFs提供了新的见解，还表明了“一锅法”策略构建多孔材料的通用性。
