A novel and simple solvent-dependent fluorescent probe based on a click generated 8-aminoquinoline–steroid conjugate for multi-detection of Cu(II), oxalate and pyrophosphate
RSC ADVANCES(2017)
摘要
In this work, a novel and simple deoxycholic acid-based fluorescent probe for solvent-dependent multi-detection of Cu2+, C2O42- and P2O74- has been facilely constructed by click chemistry. This probe displayed sensitive recognition toward Cu2+ in low-water-content CH3CN aqueous solution (CH3CNH2O, 99/1, v/v) via strong fluorescence quenching. Whereas, in DMSO-H2O medium (1/1, v/v), it exhibited significant fluorescent enhancement for C2O42- and P2O74- over a wide range of tested anions. Moreover, with low detection limits and fast response time, the developed fluorescent molecule was used successfully for analysis of the target ions on test paper strips and in water samples.
