In search of supramolecular antenna systems for light‐harvesting applications, we report on a short and effective synthesis of a fused NDI–zinc–salphen‐based chromophore (salphen = bis‐salicylimide phenylene) and its photophysical properties. A supramolecular recognition motif is embedded into the chromophoric π‐system of this compound. The fused π‐chromophore behaves as one pigment, absorbs light

intensity changes in the absorption and emission spectra. This derivative exhibits good photostability, good selectivity, high sensitivity, and is employed to exhibit the pHwithin the roughendoplasmicreticulum of livingcells.
已通过两步以高收率合成了氨基核取代的萘二亚胺 (NDI) 衍生物。带有二胺部分的 NDI 经历了一个可逆的质子化-去质子化过程,这导致吸收和发射光谱的强度变化。该衍生物具有良好的光稳定性、良好的选择性、高灵敏度,可用于显示活细胞粗面内质网内的pH值。
