Herein, we reported highly efficient light-harvesting amphiphilic supramolecular assemblies based on a tetraphenylethylene derivative (TPE-4Py), an amphiphilic sulfonatocalix[4]arene (SC4A-C6), and a sulfite fluorescent probe (SP). The obtained assemblies not only showed obvious signal amplification compared to SP alone, with an antenna effect of up to 28.1 based on highly efficient energy transfer of 75.2% from TPE-4Py/SC4A-C6 to SP, but also displayed an excellent ratiometric fluorescence signal output toward sulfites. Meanwhile, the assemblies showed no obvious cytotoxicity to A549 cells and could be used to sense sulfites in the cells. This strategy for constructing supramolecular assemblies not only resulted in a high-efficiency light-harvesting platform but also amplified the signal of the probe because of the high antenna effect and thus constitutes an effective method for fabricating fluorescent cell sensors.

基于Sulfonatocalix [4]芳烃的光捕获两亲性超分子组装体，用于检测细胞中的亚硫酸盐

在本文中，我们报道了基于四苯基乙烯衍生物（TPE-4Py），两亲性磺基杯[4]芳烃（SC4A-C6）和亚硫酸盐荧光探针（SP）的高效光捕获两亲性超分子组装体。从TPE-4Py / SC4A-C6到SP的高效能量转移达到75.2％，与单独使用SP相比，获得的组件不仅显示出明显的信号放大，而且天线效应高达28.1。，但对亚硫酸盐也显示出出色的比例荧光信号输出。同时，该组装体对A549细胞没有明显的细胞毒性，可用于感测细胞中的亚硫酸盐。这种构建超分子组装体的策略不仅产生了一个高效的光收集平台，而且由于天线效应高，还放大了探针的信号，从而构成了一种制造荧光细胞传感器的有效方法。
