主　　题：Spiropyran Probe Cerium(Ⅲ)ion Fluorescent Rare earths 

摘      要：A spiropyran-based probe was *** serves as a fluorescence turn-on probe for selective detection of Ce^3+in both ethanol and aqueous(water/ethanol,1:9 or 9:1,v/v)***3+can induce photochromism of the probe though the probe exhibits negligible photochromic property by *** probe is sensitive to Ce3+and the detection limit reaches 1.7μmol/*** exhibits a high selectivity for Ce^3+ion over other common metal cations including Li^+,Na^+,Ag^+,Sr^2+,Ni^2+,Co^2+,Hg^2+,Zn^2+,Cr^3+,Al^3+,Fe^3+and Bi^3+and lanthanide ions Nd^3+,Yb^3+and La^3+.The probe may be used for quantitative determination of the concentration of Ce3+ion in a range of 1-10μmol/L and for application to environmental water *** mechanism of the probe towards Ce3+ion is proposed.
