A New Rhodamine B-coumarin Fluorochrome for Colorimetric Recognition of Cu^2+ and Fluorescent Recognition of Fe3+ in Aqueous Media

다국어 초록 (Multilingual Abstract)

A new rhodamine B-coumarin conjugate (1) capable of recognizing both Cu^2+ and Fe^3+ using two different detection modes have been designed and synthesized. The metal ion induced optical changes of 1 were investigated in CH_3CN-H_2O (1:1, v/v, HEPES 50 mM, pH = 7.0) solution. Sensor 1 exhibits selective colorimetric recognition of Cu^2+ and fluorescent recognition of Fe^3+ with UV-vis and fluorescence spectroscopy,respectively. Moreover, both of the Cu^2+ and Fe^3+ recognition processes are observed to be barely interfered by other coexisting metal ions.
