To achieve the selectivity of luminescent sensing and gas separation, an unprecedented nanocages based 3D amino-functionalized MOF, {(Me₂NH₂)[Zn(NH₂-TCB)]}_n (ZnMOF) was constructed through ligand pre-design strategy. ZnMOF contains a unique 1D triple [Zn(COO)]_n helix chain SBU and forms 7.89 × 11.72 × 14.79 Å³ nanocages with the porosity up to 42.9%. Benefit from the outstanding thermal and chemical stabilities, the ZnMOF demonstrates considerable adsorption selectivity for CO₂/CH₄ and highly sensitive detectability to Cr(VI) anions and nitroimidazole/nitrofuran antibiotics in water. In addition, the high selective adsorption and sensing mechanisms were also explored. Therefore, ZnMOF is a multifunctional material in the efficient gas adsorption and separation, and the detection of Cr(VI) anions and nitroimidazole/nitrofuran antibiotics.

为了实现发光传感和气体分离的选择性，通过配体预设计策略构建了一种前所未有的基于纳米笼的 3D 氨基功能化 MOF，{(Me ₂ NH ₂ )[Zn(NH ₂ -TCB)]} _n ( ZnMOF ) . ZnMOF包含独特的一维三重 [Zn(COO)] _n螺旋链 SBU，形成 7.89 × 11.72 × 14.79 Å ³纳米笼，孔隙率高达 42.9%。得益于出色的热稳定性和化学稳定性，ZnMOF对 CO ₂ /CH ₄表现出相当大的吸附选择性对水中的 Cr(VI) 阴离子和硝基咪唑/硝基呋喃抗生素具有高度灵敏的检测能力。此外，还探索了高选择性吸附和传感机制。因此，ZnMOF是一种多功能材料，可用于高效的气体吸附和分离，以及 Cr(VI) 阴离子和硝基咪唑/硝基呋喃类抗生素的检测。
