摘要：

In this study, we have developed a novel ratiometric fluorescence probe (HL) which contains rhodamine and quinoline moiety. In the absence of Fe3+, the sensor displays fluorescence emission at 425 nm, in the presence of Fe3+, the sensor shows a large fluorescence enhancement at 550 nm in methanol. More importantly, the reversibility of the recognition process of HL is performed by adding a Fe3+ bonding agent Na(2)EDTA. (C) 2015 Elsevier B.V. All rights reserved.
