  • Title: Ratiometric nanomolar detection of Cu2+ ions in mixed aqueous media: a Cu2+/Li+ ions switchable allosteric system based on thiacalix[4]crown.
    Author: Kumar M, Kumar N, Bhalla V.
    Journal: Dalton Trans; 2012 Sep 14; 41(34):10189-93. PubMed ID: 22847009.
    Abstract:
    A novel ditopic fluorescent chemosensor 2, based on the 1,3-alternate conformation of thiacalix[4]crown possessing two complexation sites, was synthesized and shows ratiometric nanomolar detection of Cu(2+) ions and exhibits negative allosteric behaviour between Cu(2+)/Li(+) ions in mixed aqueous media.
