The photosynthetic pigment "chlorophyll" possesses attractive photophysical properties, including efficient sunlight absorption, photoexcited energy transfer, and charge separation, which are advantageous for applications for photo- and electro-functional materials such as artificial photosynthesis and solar cells. However, these functions cannot be realized by individual chlorophyll molecules alone; rather, they are achieved by the formation of sophisticated supramolecules through the self-assembly of the pigments. Here, we present strategies for constructing and developing artificial light-harvesting systems by mimicking photosynthetic antenna complexes through the highly ordered supramolecular self-assembly of synthetic dyes, particularly chlorophyll derivatives.
光合色素“叶绿素”具有吸引人的光物理性质，包括高效的阳光吸收、光激发能量转移和电荷分离，这有利于光功能和电功能材料的应用，如人工光合作用和太阳能电池。然而，这些功能不能仅由单个叶绿素分子实现，而是通过色素的自组装形成复杂的超分子来实现的。在这里，我们通过高度有序的超分子自组装合成染料，特别是叶绿素衍生物，模拟光合作用天线复合物，提出构建和开发人工光捕获系统的策略。
