Dendrimer-hydrazides are coupled to polycyclic aromatic hydrocarbons for use in the visual detection of the presence of low levels of fluoride in a sample. The dendrimers can have a phenyl core, a first generation of aralkyl ethers, and an optional second generation of aralkyl ethers. The compounds form gels with solvents. In the presence of fluoride ion, the gels undergo color changes and/or gel to liquid phase change.
树枝状聚合物-肼酸酯与多环芳烃偶联,用于可视检测样品中低水平氟化物的存在。这些树枝状聚合物可以具有苯基核心,第一代芳基醚,以及可选的第二代芳基醚。这些化合物与溶剂形成凝胶。在氟离子存在的情况下,凝胶会发生颜色变化和/或凝胶向液相转变。
