Research on dye molecules has been continuing to be at the forefront of new developments in chemistry owing to their versatile functional properties associated with -conjugation. On a supramolecular level, appropriately controlled spatial arrangement of dyes enables pivotal functions in nature, the most intriguing examples being provided by the light-harvesting systems of purple and green bacteria which contain a large number of chlorophyll and carotene chromophores organized in cyclic arrays or tubular architectures by non-covalent interactions. During the last few years, we have intensively investigated the organization of merocyanine, chlorin, squaraine, and perylene bisimide dyes by non-covalent forces into desirable nanoscale architectures as well as liquid-crystalline and crystalline solid state materials. In this lecture, I will provide an overview on our achievements in the preparation of defined dye assemblies and their suitability as building blocks for artificial photosynthesis and photovoltaics. 1-4
