  • Title: Tris(triazole) tripodal receptors as selective probes for citrate anion recognition and multichannel transition and heavy metal cation sensing.
    Author: González Mdel C, Otón F, Espinosa A, Tárraga A, Molina P.
    Journal: Org Biomol Chem; 2015 Feb 07; 13(5):1429-38. PubMed ID: 25469759.
    Abstract:
    The three-armed pyrenyl-triazole receptor 1 behaves as a highly selective fluorescent molecular sensor for citrate anions over similar carboxylates such as malate or tartrate. In addition, this receptor senses Cu(2+) cations through absorption and emission channels even in the presence of Hg(2+) metal cations. The related three-armed ferrocenyl-triazole receptor 2 behaves as a highly selective dual (redox and chromogenic) chemosensor molecule for Pb(2+) metal cations.
