The leaf is a prime example of a material converting waste (CO ) into value with maximum sustainability. As the most important constituent, it contains the coupled photosystems II and I, which are imbedded in the cellular membrane of the chloroplasts. Can key functions of the leaf be packed into soap? We present next-generation surfactants that self-assemble into bilayer vesicles (similar to the cellular membrane), are able to absorb photons of two different visible wavelengths, and exchange excited charge carriers (similar to the photosystems), followed by conversion of CO (in analogy to the leaf). The amphiphiles contain five dye molecules as the hydrophobic entity attached exclusively to one hemisphere of a polyhydroxylated fullerene (Janus-type). We herein report on their surfactant, optical, electronic, and catalytic properties. Photons absorbed by the dyes are transferred to the fullerenol head, where they can react with different species such as CO to give formic acid.
叶子是将废物（CO）转化为具有最大可持续性价值的主要材料。作为最重要的组成部分，它包含耦合的光系统 II 和 I，这些系统嵌入在叶绿体的细胞膜中。叶子的关键功能能否封装在肥皂中？我们提出了新一代表面活性剂，它们可以自组装成双层囊泡（类似于细胞膜），能够吸收两个不同可见波长的光子，并交换激发的载流子（类似于光系统），然后将 CO 转化（类似于叶子）。两亲物含有五个染料分子作为疏水分子实体，专门附着在多羟基富勒烯（Janus 型）的一个半球上。本文报道了它们的表面活性剂、光学、电子和催化性质。染料吸收的光子被转移到富勒醇头部，在那里它们可以与不同的物质（如 CO）反应生成甲酸。
