Program | DNA is increasingly used as a scaffold for the construction of multi-chromophore arrays since ordered ensembles possess different properties than the monomeric units. During the last few years the use of non-nucleosidic polyaromatic building blocks was shown to form extended interstrand-stacked arrays in DNA double strands. This approach allowed the construction of stable and well-defined Pi-stacks with intrinsic properties. These specific properties rendered the Pi-stacks an interesting and versatile tool for the use in different fields. Recently the combination of phenanthrene and pyrene building blocks showed a potential application as light harvesting antennas. | |
