【 摘 要 】

A new rhodamine B-coumarin conjugate (1) capable of recognizing both Cu2+ and Fe3+ using two different detection modes have been designed and synthesized. The metal ion induced optical changes of 1 were investigated in CH3CN-H2O (1:1, v/v, HEPES 50 mM, pH = 7.0) solution. Sensor 1 exhibits selective colorimetric recognition of Cu2+ and fluorescent recognition of Fe3+ with UV-vis and fluorescence spectroscopy, respectively. Moreover, both of the Cu2+ and Fe3+ recognition processes are observed to be barely interfered by other coexisting metal ions.
