  • Title: A dual colorimetric and fluorometric sensor for lead ion based on conjugated polydiacetylenes.
    Author: Lee KM, Chen X, Fang W, Kim JM, Yoon J.
    Journal: Macromol Rapid Commun; 2011 Mar 16; 32(6):497-500. PubMed ID: 21433205.
    Abstract:
    A PDA based sensor, derived from a di-(2-picolyl) amine (DPA) substituted diacetylene monomer, displayed a selective colorimetric change and a large fluorescence enhancement in the presence of lead ions. The lead selective PDA-based chemosensor enabled easy detection of the presence of lead in 100% aqueous solution by the naked-eye.
