摘要：

Detecting Sn2+ 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 Sn2+ ion, displaying high selectivity and a low detection limit of 0.121 mu M. The synthesis and application of this molecule offer a potential strategy for preventing environmental health risks.
