A hybrid molecular photovoltaic system, based on fullerene C(60) and lutein (a natural photosynthetic carotenoid pigment) that are assembled in a phospholipid/alkanethiol bilayer matrix, is described here. The assembly and photoconversion behaviors of such a system were studied by UV-vis spectroscopy, cyclic voltammetry, impedance spectroscopy, photoelectrochemical action spectroscopy, and photocurrent generation. While lutein itself is inefficient in generating photocurrent, it can strongly modulate photocurrents produced by fullerenes when coassembled in the lipid bilayer matrix presumably via photoinduced electron transfer. Our results thus provide a successful example of combining both synthetic and natural photoactive components in building molecular photovoltaic systems.
这里描述了一种基于富勒烯 C(60)和叶黄素（一种天然光合类胡萝卜素色素）的混合分子光伏系统，它们组装在磷脂/硫醇双层基质中。通过紫外可见光谱、循环伏安法、阻抗谱、光电化学作用光谱和光电流产生研究了这种系统的组装和光转化行为。虽然叶黄素本身产生光电流的效率不高，但当它在脂质双层基质中共组装时，它可以通过光诱导电子转移强烈调节富勒烯产生的光电流。因此，我们的结果提供了一个成功的例子，即将合成和天然光活性成分结合在构建分子光伏系统中。
