摘要：

A rich harvest: A visible-light-harvesting system has been created utilizing an organogel medium (see picture; the inset shows different gel mixtures). Mixing four different perylene derivatives in the gel phase sets up an energy gradient in the gel fibrils. The well-defined nanofibers harvest a wide range of light energy in the visible region (i.e., sunlight) to the energy sink in a stepwise manner.
