In the light harvesting system of purple bacteria hundreds of chromophores are hierarchically organized in cyclic arrays within a 2D membrane. In this project we aim to construct a similar but fully artificial system based on perylene bisimide dyes that are first organized in trimers to provide metallacycles containing three perylene bisimide and up to twelve additional antenna dyes. The optical and photophysical properties of these supramolecular dye assemblies are investigated by UV/Vis and fluorescence spectroscopy and, in particular, by single-molecule spectroscopy. In the subsequent step these trimeric units are self-assembled on surfaces to give 2D patterns of interacting ultichromophoric subunits.

在紫色细菌的捕光系统中，数百个发色团在2D膜内以环状阵列分层组织。在这个项目中，我们的目标是构建一个类似的，但完全人工系统的基础上，苝双酰亚胺染料，首先组织在三聚体，以提供含有三个苝双酰亚胺和多达12个额外的天线染料的金属杂环。这些超分子染料组件的光学和物理性质的研究通过UV/维斯和荧光光谱，特别是通过单分子光谱。在随后的步骤中，这些三聚体单元在表面上自组装，以给出相互作用的多发色团亚基的2D图案。
