英文摘要	The creation of defects into luminescent MOFs allows for manipulation of fluorescent properties and thus leads to the enhanced detection performance for technological applications. Herein, a modulator-induced defect formation strategy was proposed to introduce missing-linker defect into lanthanide-based metal-organic framework (Eu@UiO-MOFs) and the enhanced detection properties was investigated. Notably, the missing-linker numbers in per Zr-6 cluster were calculated to facilitate comparison and quantitively interpretation. By elaborately tailoring defect numbers, the resultant Eu@UiO-MOFs-2 sensor with 0.53 missing linkers per Zr-O cluster showed a remarkably enhanced response slope and realized excellent trace detection under the range of 0-10 ppm with ultralow detection limit to 5.67 x 10(-7) M (114 ppb), acting as a powerful signal amplifier for trace detection of Cd2+. Moreover, the relationship between structural change and defect numbers of Eu@UiO-MOFs-X has been studied to understand the positive effect of the improved enrichment for the optical behavior. As far as we know, this is the first experimental demonstration of missing-linker defects in luminescent MOFs for regulation of optical sensing, offering a unique approach to explore innovative technologies for precisely detecting of heavy metal ion pollutants.
