Abstract The selective detection and separation of target ions or molecules is an intriguing issue. Herein, a novel supramolecular organic framework ( SOF‐ T H BP ) was constructed by bis‐thioacetylhydrazine functionalized pillar[5]arenes. The SOF ‐ T H BP shows a fluorescent response for Fe 3+ , Cr 3+ , Hg 2+ and Cu 2+ ions. The xerogel of SOF ‐ T H BP shows excellent recyclable separation properties for these metal ions and the absorption rates were up to 99.29 %. More interestingly, by rationally introducing these metal ions into the SOF ‐ T H BP , a series of metal‐ion‐coordinated SOFs (MSOFs) such as MSOF‐Fe , MSOF‐Hg and MSOF‐Cu were constructed. These metal ions coordinated MSOFs could selectively sense F − , Br − , and l ‐Cys, respectively. The detection limits of these MSOFs for F − , Br − and l ‐Cys were about 10 −8 m.
