An AIE fluorescence probe for ratiometric and selective detection of Sn2+ based on proton transfer
Detecting Sn<sup>2+</sup> heavy metal ions is crucial for mitigating water pollution and safeguarding human health. This study involved the design and synthesis of a novel fluorescence probe, RTPE-IM, which is a combination of an aggregation-induced emission luminophore (TPE) and rhodamine B. The probe undergoes proton transfer in the presence of Sn<sup>2+</sup> ion, displaying high selectivity and a low detection limit of 0.121 μM. The synthesis and application of this molecule offer a potential strategy for preventing environmental health risks.
