  • Title: A new rhodamine based colorimetric 'off-on' fluorescence sensor selective for Pd2+ along with the first bound X-ray crystal structure.
    Author: Goswami S, Sen D, Das NK, Fun HK, Quah CK.
    Journal: Chem Commun (Camb); 2011 Aug 28; 47(32):9101-3. PubMed ID: 21731939.
    Abstract:
    A new fluorescence rhodamine derivative bearing an 8-aminoquinoline moiety has been designed and synthesized for selective sensing of Pd(2+) in the presence of other competing metal ions in aqueous media. Pd(2+) induced spirolactam ring opening of rhodamine is confirmed for the first time by the X-ray crystal structure of the bound Pd(2+)-complex.
