| 摘 要： | Two novel rhodamine-based fluorescence enhanced molecular probes (RA1 and RA2) were synthesized, which were both designed as comparative fluoroionophore and chromophore for the optical detection of Hg2+. The recognizing behaviors were investigated both experimentally and computationally. They exhibited high selectivity and sensitivity for Hg2+ over other commonly coexistent metal ions in CH3CN/H2O (1:1, V/V) solution. Test shows that hydroxy benzene of rich electron was beneficial to the chelate of Hg2+ with sensors. The detection limit was measured to be at least 0.14 μmol/L. After addition of Hg2+, the color changed from colourless to pink, which was easily detected by the naked eye in both solution and hydrogel sensor.
