合成了两种新型阴离子In-MOFs V101和V102，并对其进行了结构表征。通过将溶剂从DMF变为DEF，完成了从2倍互穿到非互穿的结构转变。发光研究表明，V102而不是V101能够以环境友好的方式对水溶液中痕量抗生素硝基呋喃酮进行敏感和选择性检测，检出限可达0.2 ppm。V101和V102的发光差异主要来源于穿透间结构的差异。即通过互穿控制，发光探针可以开启或关闭来检测硝基呋喃酮。这是基于mfs的互穿相关发光探针的第一个例子。
Two novel anionic In-MOFs V101 and V102 were synthesized and structurally characterized. The structrual transformation from 2-fold interpenetration to noninterpenetration was completed by changing solvent from DMF to DEF. Luminescence investigations reveal that only V102 not V101 can sensitively and selectively detect traces of antibiotics nitrofurazone in water solution via an environmentally friendly manner, and the detection limit can reach to 0.2 ppm. The luminescent difference between V101 and V102 mainly originates from the divergence of interpenetration structures. Namely, through interpenetration control, the luminescent probe can switch on or off to detect nitrofurazone. This is the first example of interpenetration-dependent MOFs-based luminescent probe.
