  • Title: Construction of fluorescent probes via protection/deprotection of functional groups: a ratiometric fluorescent probe for Cu2+.
    Author: Lin W, Yuan L, Tan W, Feng J, Long L.
    Journal: Chemistry; 2009; 15(4):1030-5. PubMed ID: 19053103.
    Abstract:
    Herein a ratiometric fluorescent Cu(2+) probe was rationally constructed in a straightforward manner with the concept of aldehyde group protection/deprotection. The probe showed a ratiometric fluorescent response to Cu(2+) with a large emission wavelength shift (>100 nm) and displayed high selectivity for Cu(2+) over other metal ions due to distinct deprotection conditions. In addition, a Cu(2+)-promoted dethioacetalization mechanism was proposed.
