Novel imidazole-functionalized polysiloxane (PMMS-IM) was synthesized by facile thiol-ene “click” chemistry. PMMS-IM exhibited strong photoluminescence excited by a wavelength of 365 nm. In addition, the consecutive response to Fe³⁺ and amino acids by fluorescence quenching and lighting has been investigated. The sequence response of PMMS-IM towards Fe³⁺ and amino acids exhibit fine selectivity. Moreover, PMMS-IM represented a useful tool for monitoring the Fe³⁺/amino acids cycle in situ in lived HeLa cells. This work represented the first example for the consecutive detection of Fe³⁺ and amino acids based on polysiloxanes. The presented investigation illustrated a promising approach towards the ultilizing of functionalized polysiloxanes as a novel kind of appealing fluorescent probes.

新型的咪唑官能化聚硅氧烷（PMMS-IM）是通过容易的硫醇-烯“点击”化学反应合成的。PMMS-IM表现出由365 nm波长激发的强光致发光。另外，已经研究了通过荧光猝灭和照明对Fe ³⁺和氨基酸的连续响应。PMMS-IM对Fe ³⁺和氨基酸的序列响应表现出良好的选择性。此外，PMMS-IM代表了一种有用的工具，可用于监测活HeLa细胞中Fe ³⁺ /氨基酸的原位循环。这项工作代表了连续检测Fe ³⁺的第一个例子和基于聚硅氧烷的氨基酸。提出的研究表明了一种将功能化聚硅氧烷用作一种新颖的荧光探针的有前途的方法。
