4187 1000 A nanosized metal–organic framework for visual detection of fluoride ions with smartphone via colorimetric test kit https://doi.org/10.1016/j.snb.2021.129508 MOF We rationally developed the nanosized iron-based metal organic frameworks (Fe-MOFs) by using 3,5-dicarboxybenzeneboronic acid as organic linkers and Fe3+ as metal ions through the solvothermal method, which can be applied for detecting F− with high sensitivity and selectivity owing to the specific recognition of boronic acid groups towards F− and the strong binding affinity between F− and Fe3+.
