  • Title: Cu2+-selective ratiometric and "off-on" sensor based on the rhodamine derivative bearing pyrene group.
    Author: Zhou Y, Wang F, Kim Y, Kim SJ, Yoon J.
    Journal: Org Lett; 2009 Oct 01; 11(19):4442-5. PubMed ID: 19775186.
    Abstract:
    A new rhodamine-based derivative bearing a pyrene group (PRC) was synthesized as a ratiometric and "off-on" chemosensor for Cu(2+). PRC displayed a selective and chelation enhanced ratiometric fluorescence change and colorimetric change with Cu(2+) among the metal ions examined.
