The supramolecular self-assembly of pyrene-DNA conjugates into nanostructures is presented. DNA functionalized with different types of pyrene isomers at the 3'-end self-assemble into nano-objects. The shape of the nanostructures is influenced by the type of pyrene isomer appended to the DNA. Multilamellar vesicles are observed with the 1,6- and 1,8-isomers, whereas conjugates of the 2,7-isomer exclusively assemble into spherical nanoparticles. Self-assembled nano-spheres obtained with the 2,7-dialkynyl pyrene isomer were used for the construction of an artificial light-harvesting complex (LHC) in combination with Cy3 as the energy acceptor.
呈现了一种将芘-DNA 缀合物超分子自组装成纳米结构的方法。在 3' 端用不同类型的芘异构体功能化的 DNA 自组装成纳米物体。纳米结构的形状受附加到 DNA 的芘异构体类型的影响。观察到具有 1,6-和 1,8-异构体的多层囊泡，而 2,7-异构体的缀合物则专门组装成球形纳米颗粒。用 2,7-二炔基芘异构体获得的自组装纳米球被用于与 Cy3 作为能量受体结合构建人工光捕获复合物 (LHC)。
