Highly selective recognition of Al3+ and I ions using a bi-functional fluorescent probe

Author affiliations

Abstract

A tripodal fluorescent probe L1 armed with Rhodamine B and 1-naphthaleneisothiocyanates was prepared in high yield. A study of the recognition properties revealed that probe L1 exhibited high sensitivity and selectivity towards Al3+ through a “FRET” fluorescence response and colorimetric response with low detection limits of the order of 10−8 M. Meanwhile, probe L1 also possessed high recognition ability for I through fluorescence decay, which given there are comparatively few selective fluorescent probes for I, is significant. Furthermore, the complexation mechanisms were fully investigated by spectral titrations, 1H NMR spectroscopic titrations and mass spectrometry. The utility of probe L1 as a biosensor in living cells (PC3 cells) towards Al3+ ions has also been demonstrated.
