The self-assembly of highly functionalized phenanthrene-DNA conjugates into supramolecular nanostructures is presented. DNA oligomers modified with phenanthrene residues at the 3'-end and internal positions self-assemble into spherical nanostructures. The nanospheres exhibit light-harvesting properties. Upon irradiation of phenanthrene, the excitation energy is transferred along phenanthrene units, resulting in phenanthrene-pyrene exciplex formation.
本文介绍了高度功能化的菲 - DNA 共轭物自组装成超分子纳米结构的过程。在 3' 端和内部位置用菲残基修饰的 DNA 寡聚物自组装成球形纳米结构。这些纳米球具有光捕获特性。在菲受到照射时,激发能沿着菲单元转移,导致菲 - 芘激基复合物的形成。
