  • Visual detection of fluoride ions
    Patent number: 9201001
    Abstract: 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.
    Type: Grant
    Filed: August 14, 2014
    Date of Patent: December 1, 2015
    Assignee: Indian Institute of Technology Madras
    Inventors: Prasad Edamana, Rajamalli Pachaiyappan
