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 between 600 and 750 nm and displays a modest Stokes shift. Upon binding pyridines, the compound (DATZnS) does not change its redox potentials, does not undergo any internal excited state quenching and does not appreciably alter its excited state lifetime. These notable properties define DATZnS as an alternative to porphyrin-based components used in supramolecular light-harvesting architectures.
为了寻找用于光捕获应用的超分子天线系统，我们报道了一种基于稠合萘二亚胺-锌-水杨醛缩邻苯二胺的发色团（水杨醛缩邻苯二胺=双水杨酰亚胺亚苯基）的简短有效合成方法及其光物理性质。一种超分子识别基序嵌入到该化合物的发色π体系中。稠合π发色团表现为一种色素，在600至750nm之间吸收光，并显示出适度的斯托克斯位移。在结合吡啶时，该化合物（DATZnS）不会改变其氧化还原电位，不会发生任何内部激发态猝灭，并且不会明显改变其激发态寿命。这些显著特性将DATZnS定义为超分子光捕获结构中使用的基于卟啉的组件的替代品。
