  • Calix[4]arenes for the selective detection of Zn
    Patent number: 8148158
    Abstract: Calix[4]arenes of Formula I are useful for selectively detecting Zn2+ ion.
    Type: Grant
    Filed: February 8, 2011
    Date of Patent: April 3, 2012
    Assignee: Indian Institute of Technology Bombay
    Inventors: Chebrolu Pulla Rao, Rakesh Kumar Pathak
  • Selective detection of Hg2+ by calix[4]arenes
    Patent number: 8034622
    Abstract: Provided herein are compounds, methods of making the compounds and methods for the sensitive and selective detection of Hg2+ with the compounds, which are calix[4]arenes. In particular, compounds of Formula I, wherein the variables have the values described herein, may be added to a sample to be tested for Hg2+. The compound of Formula (I) fluoresces strongly in the absence of Hg2+ but is quenched upon binding of Hg2+ to form a complex. The decrease in fluorescence may be used to detect and quantify the amount of Hg2+ present in a sample. The disclosed compounds may also be used to selectively detect Hg2+ in samples containing other mono- or divalent metals.
    Type: Grant
